How are tadpoles and larvae similer

Tadpole, also called polliwog, aquatic larval stage of frogs and toads. Compared with the larvae of salamanders, tadpoles have short, oval bodies, with broad tails, small mouths, and no external gills. The internal gills are concealed by a covering known as an operculum.

Explanation:

In a dynamic equilibrium, the rate of the forward reaction is equal to the rate of the backward reaction. In the case of evaporation, if this is considered as the forward reaction, then the backward reaction is condensation. Hence, dynamic equilibrium occurs when the rate of evaporation is equal to the rate of condensation. Answer is C.
