c.
dense, wooly coats; horns to dig for food; specially adapted feet; migrate during winter
d.

c.

Reason: Wild yaks have dense woolly coats for insulation, horns they use to dig through snow for forage, specially adapted feet/hooves for walking on rocky, icy ground, and they make seasonal (altitudinal) movements rather than hibernating.
