In a specific habitat, male moose (bulls) grow antlers during the warm spring seasons

In a specific habitat, male moose (bulls) grow antlers during the warm spring seasons and shed them during the harsh winter months. Mainly used to scare competition during mating season, the antlers are eventually shed between November and March. The chart below illustrates four types of moose in a population of bulls during a typical mating season. Screen
Due to natural selection, how will the population of male bulls change in this habitat over time?

The population of Moose B and C will increase since they can compete for males.
⊝

The population of Moose B will be extinct since they cannot compete with Moose C and D.
⊝

There will be an increase in the population of Moose D since those with larger antlers are better able to compete for mates.
⊝

Moose A will have a greater chance of survival since there are initially more than Moose B and D.
