Which of the following, if true, would argue against long necks being an adaptation in giraffes?

a. males compete for the opportunity to mate with females by striking each other. males with longer necks deliver more powerful strikes to their opponents than males with shorter necks.
b. long necks allow giraffes to feed on higher vegetation that giraffes with shorter necks cannot reach
c. shorter-necked giraffes have more sturdy necks and are more likely to win head-striking contests, winning the opportunity to mate with females.
d. longer-necked giraffes are faster and less susceptible to predation

b. Long necks allow giraffes to feed on higher vegetation that giraffes with shorter necks cannot reach.

Explanation:

The natural selection is the phenomena of differential survival as well as reproduction which can be seen in the population of the same species. This is due to the fact that some organisms of the species posses better phenotypic traits over the others which helps them to survive and reproduce. These traits are passed on from parents to their offsprings.

The example of natural selection is the development of the giraffe neck. Some of the giraffe organisms developed long neck which helped them to grab leaves from tall trees in the scarcity of food at the ground level. This beneficial trait was passed on to the successive generations of giraffes.
