Solution(By Examveda Team)

Inbreeding depression is highest in Carrot.
Inbreeding depression is one of the leading factors preventing the evolution of self-fertilization in plants. In populations where self-fertilization evolves, theory suggests that natural selection against partially recessive deleterious alleles will reduce inbreeding depression.
Inbreeding depression is high in a self-incompatible perennial herb population like a carrot but absents in a self-compatible population showing mixed mating.
