Correct option is C
Both statements A and B are incorrect. Crows typically build their nests on high branches of trees, not on very low branches. This positioning helps protect their nests from predators and provides a good vantage point. On the other hand, the weaver bird does not stitch two leaves together to make its nest. Weaver birds are known for their intricate nests, which they weave from grass, twigs, and other plant materials. These nests are often complex structures that hang from branches, providing safety from ground predators.
