Question

what physical signs does a horse exhibit if it is very interested in something?
their tail flicks up and down or side to side.
their eyes are relaxed, and the ears will lay low.
their eyes are fixed, and ears are pricked up.
their ears are pinned back while they also paw at the ground.

Explanation:

To determine the correct answer, we analyze the typical behavioral signs of a horse when interested. A horse showing interest will focus its attention, so fixed eyes (concentrating) and pricked - up ears (to listen/attend) are indicative. Tail flicking can be a sign of agitation or other states, relaxed eyes and low - laying ears suggest calmness or disinterest, and pinned - back ears with pawing are signs of aggression or irritation.

Answer:

C. Their eyes are fixed, and ears are pricked up.
