Question

Match LIST-I with LIST-II

LIST-I	LIST-II
A. Pituitary B. Pineal C. Thyroid D. Parathyroid	I. Controls Metabolism II. Master gland of endocrine system III. Glands behind Thyroid IV. Gland makes a chemical called Melatonin

Choose the correct answer from the options given below:

• A. A-I, B-II, C-III, D-IV
• B. A-III, B-I, C-II, D-IV
• C. A-II, B-IV, C-I, D-III
• D. A-IV, B-III, C-II, D-I

Hint:

Important endocrine gland functions: \[ \text{Pituitary} \rightarrow \text{Master gland} \] \[ \text{Pineal} \rightarrow \text{Melatonin secretion} \] \[ \text{Thyroid} \rightarrow \text{Controls metabolism} \] \[ \text{Parathyroid} \rightarrow \text{Located behind thyroid} \]

Answer 1

The Correct Option is C

Concept: The endocrine system consists of glands that secrete hormones directly into the bloodstream. Each gland has a specific physiological role in regulating growth, metabolism, reproduction, sleep cycle, and calcium balance. The question asks to correctly match endocrine glands with their major functions or characteristics.

Step 1: Match Pituitary gland.
The pituitary gland regulates and controls many other endocrine glands, therefore it is called: \[ \text{Master gland of endocrine system} \] Thus: \[ A \rightarrow II \]

Step 2: Match Pineal gland.
The pineal gland secretes: \[ \text{Melatonin} \] which regulates sleep and circadian rhythm. Thus: \[ B \rightarrow IV \]

Step 3: Match Thyroid gland.
The thyroid gland regulates: \[ \text{Metabolism} \] through thyroid hormones. Thus: \[ C \rightarrow I \]

Step 4: Match Parathyroid gland.
Parathyroid glands are located: \[ \text{Behind the thyroid gland} \] Thus: \[ D \rightarrow III \]

Step 5: Write the final matching.
The correct matching is: \[ A \rightarrow II \] \[ B \rightarrow IV \] \[ C \rightarrow I \] \[ D \rightarrow III \] Therefore: \[ \boxed{\text{A-II, B-IV, C-I, D-III}} \]

Step 6: Identify the correct option.
The option matching the correct sequence is: \[ \boxed{\text{A-II, B-IV, C-I, D-III}} \] Hence, the correct answer is: \[ \boxed{(C)} \]
