Answer:
Correct Answer: B
Solution:
Excretory fluid of Pila contains mostly ammonia and some ammonium compounds, urea and uric acid.
Pila shows an adaptation for water conservation during terrestrial phases by converting ammonia into the insoluble uric acid.
During aquatic phase, Pila excretes ammonia (as it requires maximum water availability), but during terrestrial phase (due to the deficiency of water), it excretes uric acid.
So it is both ammonotelic as well as uricitelic.
