Which statement explains a variation in the leaves that affects the plants’ probability of surviving at the ground level of this forest?

• Plants with round leaves are more likely to survive than plants with oval leaves, because round leaves gather water better.

• Plants with thick leaves are more likely to survive than plants with thin leaves, because more minerals are stored in the plants’ leaves.

• Plants with large leaves are more likely to survive than plants with small leaves, because more solar energy is captured in the plants’ leaves.

• Plants with few leaves are more likely to survive than plants with many leaves, because all of the chloroplasts are concentrated.
