D. None of the above.

Correct Answer » B Explanation

The embryological structure shown as 2 in the photograph above represents Paramesonephric duct.

Paramesonephric ducts (or Müllerian ducts) are paired ducts of the embryo that run down the lateral sides of the urogenital ridge and terminate at the sinus tubercle in the primitive urogenital sinus. In the female, they will develop to form the uterine tubes, uterus, cervix, and the upper one-third of the vagina. In the male, they are lost. These ducts are made of tissue of mesodermal origin.
