These four bird species are closely related, and all of them share a common ancestor with a single species. What environmental factor is most likely to have caused this diversity of species?

When the ancestral species arrived at the island, there was only one food source, so the ancestral species left the island immediately.

When the ancestral species arrived at the island, there was only one food source available and no need for different beak shapes.

When the ancestral species arrived at the island, there were multiple food sources available, and different beak shapes evolved for the most efficient eating.

When the ancestral species arrived at the island, there were multiple food sources available, and the different beak shapes were equally efficient for eating different food sources.

The environmental factor most likely to have caused the diversity of species among the bird species on the island is:
When the ancestral species arrived at the island, there were multiple food sources available, and different beak shapes evolved for the most efficient eating.
This scenario suggests that the availability of diverse food sources led to adaptive radiation, where different beak shapes evolved to utilize these resources efficiently, resulting in the diversification of the species.
