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.
