When heavily armored marine sticklebacks have invaded freshwater lakes where there are no predatory fish, their populations have evolved lighter body armor. Given what you've learned about evolution, which of the following explanations for why this happens is most plausible?
a. Young sticklebacks only grow heavy armor when they see predatory fish in their environment.
b. When sticklebacks don't use their armor, it shrinks. Then they pass lighter armor to their offspring.
c. Concentrated pollutants in freshwater lakes disrupt the sticklebacks' ability to grow armor.
d. Heavily armored fish grow more slowly and breed later, making armor disadvantageous in these lakes.
