Answer:
<em>The correct option is C) OH</em>
Explanation:
In the field of chemistry, radicals can be described as atoms, molecules or ions which have at least one unpaired electron.
The formation of a radical occurs when a single covalent bond breaks so that each of the atoms that had been involved in the formation of the covalent bond can have an unpaired electron. Examples of radicals include OH, NH4+ etc.
Other option, like option B, is not true because a molecule of water does not have any unpaired electrons in its valence shell.

Answer:
A) They occupy different niches due to competition for food.
Explanation:
According to Joseph Grinnel - "An ecological niche is the distributional unit within which each species is held by its structural and instinctive limitation. No two species in the same general territory can occupy the same ecological niche". Hence, the two lizard species have separated their trophic niches i.e. the ecological niche in which they feed, as they both have common preys that is the insects. this will avoid competition and would provide enough food for both the species.
