In an agricultural field where pesticides are regularly sprayed, there are always some insects

that survive due to some innate resistance based on their genetic makeup. These are the ones
that then reproduce so that in future generations there are more insects/pests that are resistant
to the pesticides. Over time, this may give rise to an entire population that is resistant to the
pesticide. This is an example of



a. homology.
b. natural selection.
c. experimentation.
d. classification
