Match the hormones in List-I with their chemical nature in List-II. List-I List-II (A) Insulin (I) Steroid hormone (B) Cortisol (II) Iodothyronine (C) Epinephrine (III) Peptide hormone (D) Thyroxine (IV) Amino-acid derivative Choose the correct answer from the options given below:
Options
- A(A)-(III), (B)-(IV), (C)-(I), (D)-(II)
- B(A)-(IV), (B)-(I), (C)-(III), (D)-(II)
- C(A)-(III), (B)-(I), (C)-(IV), (D)-(II)
- D(A)-(III), (B)-(I), (C)-(II), (D)-(IV)
Correct answer
C. (A)-(III), (B)-(I), (C)-(IV), (D)-(II)
Step-by-step solution
According to the NCERT classification based on their chemical nature, hormones are divided into distinct groups: Insulin is a peptide, polypeptide, or protein hormone. (A matches III) Cortisol is a steroid hormone. (B matches I) Epinephrine (adrenaline) is an amino-acid derivative (catecholamine). (C matches IV) Thyroxine is an iodothyronine. (D matches II) Therefore, the correct matching sequence is (A)-(III), (B)-(I), (C)-(IV), (D)-(II). Answer: (A)-(III), (B)-(I), (C)-(IV), (D)-(II)
