Options
- AConsist of a pair of ovary, situated near kidney and functionally connected to kidneys
- BA pair of oviduct opens into cloaca separately and female lays 25000-30000 at once
- CFertilisation is external and takes place in water
- DThere is no such larval stage
Correct answer
C. Fertilisation is external and takes place in water
Step-by-step solution
The female reproductive organs include a pair of ovaries. The ovaries are situated near kidneys and there is no functional connection with kidneys. A pair of oviduct arising from the ovaries opens into the cloaca separately. A mature female can lay 2500 to 3000 ova at a time. Fertilisation is external and takes place in water. Development involves a larval stage called tadpole. Tadpole undergoes metamorphosis to form the adult.
