Answer:
The answer is A - rolling hills.
Explanation:
Firstly piedmont is a French word which means "foot of the mountain". The biodiversity is influenced by both biotic and abotic factors. Abiotic factors are nonliving things such as temperature, sunlight, rolling hills (in this question). Biotic factors are living factors such as plants, animals and humans. So in this question all the other options are biotic factors.
