Question

Some statements regarding drugs and alcohol are given below :
(i) Adolescents are more vulnerable to peer pressure.
(ii) Drug addiction leads to increased tolerance level of the receptors present in our body.
(iii) Alcohol affects the central nervous system.
(iv) Excessive use of drugs helps to increase energy.
(v) Anabolic steroids decrease aggressiveness.
Choose the option with correct statement(s).

• A. Statements (i), (iv) and (v) are correct
• B. Statements (i), (ii) and (iii) are correct
• C. Only statements (i) and (v) are correct
• D. Only statement (iii) is correct

Hint:

You can solve this quickly by looking at statement (v). It is well known that anabolic steroids increase aggressiveness rather than decreasing it. Since statement (v) is false, you can eliminate options (A) and (C). Statement (i) is clearly true, which eliminates option (D), leaving option (B) as the correct choice.

Answer 1

The Correct Option is B

Step 1: Understanding the Question:
We are given five statements concerning the physiological and behavioral impacts of drugs and alcohol. We must identify which statements are completely accurate and select the option that groups them together.

Step 2: Key Formula or Approach:
Evaluating these statements requires applying verified physiological and psychological principles of substance abuse as outlined in behavioral health and medical biology.

Step 3: Detailed Explanation:
Let us analyze each statement systematically:
* Statement (i): "Adolescents are more vulnerable to peer pressure." This is correct. Adolescence is a transitional psychological phase characterized by curiosity, a desire for experimentation, and a strong need for social acceptance, making teenagers highly susceptible to peer influence regarding drug use.
* Statement (ii): "Drug addiction leads to increased tolerance level of the receptors present in our body." This is correct. With repeated drug exposure, the cell surface receptors in the nervous system adapt to the substance. As their sensitivity drops, the body requires higher doses to achieve the same physiological or psychological effect.
* Statement (iii): "Alcohol affects the central nervous system." This is correct. Alcohol acts as a central nervous system depressant. It binds to GABA receptors, slows down brain activity, impairs motor coordination, delays reaction times, and disrupts emotional control.
* Statement (iv): "Excessive use of drugs helps to increase energy." This is incorrect. While certain stimulants can temporarily mask fatigue, chronic abuse damages metabolic pathways, exhausts organs, and causes widespread physiological decline rather than sustainable energy production.
* Statement (v): "Anabolic steroids decrease aggressiveness." This is incorrect. The abuse of synthetic anabolic-androgenic steroids is clinically linked to increased hostility, severe mood swings, and aggressive behavior (commonly referred to as "roid rage").
Statements (i), (ii), and (iii) are completely accurate, which corresponds directly to option (B).

Step 4: Final Answer:
The option containing the correct statements is (B).
