B.Over time, more will have longer necks

Answer: Over time, more will have longer necks.

Explanation :

  • Among the two types of giraffes, the ones with longer necks have an advantage of obtaining food from tall trees as well as the grasses on the ground.
  • Due to this advantage, the tall necked giraffes are much better adapted to survive in case of calamities involving food shortage as they can obtain food from varied source.
  • Thus, the trait of the long neck will be selected by natural selection and the population of long neck giraffe will increase.
