(30 ) the ancestors of horses possessed feet with five digits. over time, with the development of grasslands, the digits fused and formed hooves. what evolutionary advantage did this transformation serve a. it allowed them to climb rocky surfaces with ease. b. it allowed them to graze better. c.,it enabled them to run faster from predators. d. it let them see clearly through the grasslands. e. it made them taller.

C. It enabled them to run faster from predators.

Explanation:

The evolution of hooves from a five-digit feet enabled horses to run faster from predators as well as support their larger weights and longer legs.

As the environment of horses's ancestors changed from protected forests to open grassland, there was a major need for them to avoid predators and their small bodies, short legs and five-digits feet would not have been able to help so much.

Hence, the horse had to evolve from small body, short legs and digit feet to bigger body, longer legs and hooves. The hooves are able to support the bigger body and the longer legs s well as enable to swing legs and gallop more efficiently to avoid predators.

The correct option is C.
