Options

  1. A(A)-(III), (B)-(II), (C)-(I), (D)-(IV)
  2. B(A)-(II), (B)-(III), (C)-(IV), (D)-(I)
  3. C(A)-(II), (B)-(III), (C)-(I), (D)-(IV)
  4. D(A)-(II), (B)-(I), (C)-(IV), (D)-(III)

Correct answer

C. (A)-(II), (B)-(III), (C)-(I), (D)-(IV)

Step-by-step solution

In a mature Graafian follicle: Zona pellucida is the inner non-cellular membrane surrounding the secondary oocyte (A matches II). Corona radiata is the outer cellular layer formed by granulosa cells that surrounds the ovum (B matches III). Antrum is the characteristic fluid-filled cavity of the tertiary and Graafian follicles (C matches I). Theca interna is the inner organised layer of the theca (D matches IV). Therefore, the correct matching is (A)-(II), (B)-(III), (C)-(I), (D)-(IV). Answer: (A)-(II), (B)-(III), (
