Match List-I with List-II :
| List-I (Biomolecule) | List-II (Function/Diseases) |
| (A) Vitamin A | (I) Menstrual cycle |
| (B) Thiamine | (II) Xerophthalmia |
| (C) Glucocorticoids | (III) Beri-Beri |
| (D) Estradiol | (IV) Addison’s disease |
Choose the correct answer from the options given below :
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → (A) - (II), (B) - (III), (C) - (IV), (D) - (I)
The list mixes two kinds of biomolecules: vitamins, whose deficiency causes a specific disease, and hormones, chemical messengers that control body functions (a fault in a gland that makes them also causes disease).
(A) Vitamin A — This matches (II) Xerophthalmia. Its deficiency causes xerophthalmia (hardening of the cornea of the eye) and night blindness.
(B) Thiamine — This matches (III) Beri-Beri. Thiamine is vitamin B1; its deficiency causes beri-beri (loss of appetite, retarded growth).
(C) Glucocorticoids — This matches (IV) Addison’s disease. Glucocorticoids and mineralocorticoids are hormones of the adrenal cortex; when the adrenal cortex does not work properly, the result can be Addison’s disease (hypoglycaemia, weakness, poor response to stress).
(D) Estradiol — This matches (I) Menstrual cycle. Estradiol is the main female sex hormone; it controls the development of female characteristics and takes part in the control of the menstrual cycle.
Shortcut: (A)–(II) appears in Options (2) and (4), and (C)–(IV) then leaves only Option (4).
Note: This question is from the pre-rationalised NCERT book (2022-23). The topic is not there in the latest NCERT book (2026-27), but it is still in the CUET 2026 syllabus, so do not skip it.
