A)Plant "A" produces either large fruit or small fruit;farmers breed only the large fruit plants,causing them to outnumber the small fruit variant.
B)Plant "B" has a rare waxy leaf variant;as the environment becomes more arid,the waxy leaf variant becomes more prevalent.
C)Plant "C" has a genetic mutation that creates a taller variant;this variant is able to survive and reproduce.
D)Plant "D" has a recessive allele that causes a higher rate of photosynthesis;plants with this phenotype have a higher energy reserve.

The scenario in choice B illustrates adaptation because the rare waxy leaf variant becomes more prevalent in response to the environment becoming more arid. This is an example of natural selection where the trait that provides an advantage in the environment becomes more common in the population over time.
