How Likely Is It That Organisms Will Respond to Rapid

How likely is it that organisms will respond to rapid climate change by undergoing short-term evolutionary adaptations?

A) It is very likely;all organisms respond to environmental change through evolution.
B) It is very likely;the rate of evolution will speed up to accommodate rapid climate change.
C) It is very likely;populations are much more likely to respond to short-term changes than to long-term ones.
D) It is not very likely;evolution will not begin to occur until it is clear that climate change is a long-term process.
E) It is not very likely;evolution occurs continually,but it may be too slow,or a population's genetic variation may be too small,to keep up with rapid climate change.
