Question

Direction - For the below Assertion [As] and Reason [R], choose the correct alternative-
Assertion [As] : Carbohydrates provide energy to the body.
Reason [R] : Obesity is caused by excessive intake of carbohydrates.

• A. Both [As] and [R] are true, and [R] is the correct explanation of [As].
• B. Both [As] and [R] are true, but [R] is not the correct explanation of [As].
• C. [As] is true, but [R] is false.
• D. [As] is false, but [R] is true.

Hint:

Ask yourself: "Does the reason answer the 'Why' of the assertion?"
Why do carbohydrates provide energy? Because they are broken down into glucose.
Since the given Reason does not answer this question, [R] is not the correct explanation of [As].

Answer 1

The Correct Option is B

Step 1: Understanding the Question:
We need to determine the individual truth values of the Assertion [As] and Reason [R] and analyze if there is a correct causal relationship between them.

Step 2: Detailed Explanation:
- Let us evaluate the Assertion [As]: "Carbohydrates provide energy to the body." This is biologically correct. Carbohydrates are digested and converted into glucose, which is the primary source of fuel/energy for the body's cells.
- Let us evaluate the Reason [R]: "Obesity is caused by excessive intake of carbohydrates." This is also biologically correct. Excess carbohydrate intake leads to high blood glucose levels, which are converted and stored as adipose tissue (fat) in the body, eventually causing obesity.
- Now let us check for a causal connection:
Does the body get energy from carbohydrates because excessive intake causes obesity? No. The metabolic process of energy release from carbohydrates (respiration) is independent of the fact that excess storage causes obesity.
Therefore, while both statements are true, the Reason is not the correct explanation of the Assertion.

Step 3: Final Answer:
(B) Both [As] and [R] are true, but [R] is not the correct explanation of [As].
