Final Answer :
B
Explanation :
Bipedalism does not provide an advantage in increased exposure to ultraviolet sun radiation. In fact, bipedalism led to the evolution of sweat glands and hair loss, which provided better cooling mechanisms but also left humans more susceptible to sunburn and skin damage. The other choices listed (A, C, and D) are all advantages of bipedalism.
