Match List-I with List-II:

Choose the correct answer from the options given below:

The correct option is (A)- (II), (B)- (III), (C)- (IV), (D)- (I).

To find the correct match, let us analyze the biological functions and related diseases associated with each biomolecule listed in List-I:

• (A) Vitamin A: Vitamin A is crucial for maintaining healthy vision and cellular health. A severe deficiency of Vitamin A leads to Xerophthalmia, a medical condition in which the eyes fail to produce tears, leading to dryness and potential blindness. Thus, (A) matches with (II).
• (B) Thiamine: Thiamine, also known as Vitamin B₁, is essential for glucose metabolism and nerve function. Its deficiency leads to the disease Beri-Beri, which affects the circulatory and nervous systems. Thus, (B) matches with (III).
• (C) Glucocorticoids: Glucocorticoids are steroid hormones secreted by the adrenal cortex that regulate metabolism and immune function. Hyposecretion or deficiency of these hormones causes Addison's disease, characterized by fatigue, low blood pressure, and hyperpigmentation. Thus, (C) matches with (IV).
• (D) Estradiol: Estradiol is the primary female sex hormone belonging to the estrogen family, and it plays a key role in regulating the female reproductive system and the Menstrual cycle. Thus, (D) matches with (I).

Combining all the matched pairs, we obtain:
(A) - (II)
(B) - (III)
(C) - (IV)
(D) - (I)
