Answer: d. The giraffes with the longest necks survive and produce offspring.

Natural selection can be defined as a differential survival and reproduction. In this the organism having a favorable phenotypic advantage has better chances of survival and reproduction as compared to the other. The given situation is an example of natural selection. The long neck of giraffes is a phenotypic advantage that helps in deriving food as compared to it's competing herbivorous species. Thus, giving them a chance to survive and produce offsprings.
