Answer 1

Answer: (C)

2 and 3 are correct, while 1 and 4 are incorrect.

The medulla oblongata passes out through the foramen magnum and continues into the spinal cord, which is enclosed in the vertebral column.

Vasa efferentia are 10 -12 in number that arises from testes.

Ovaries are situated near the kidneys and there is no functional connection with the kidneys.
Frog secretes urea and hence is ureotelic and not uricotelic.
Thus, the correct answer is option C.
