Answers (1)
Statement II, which states that higher organisms predominantly engage in asexual reproduction, suggests that intricate sexual reproductive mechanisms might have emerged later in organic evolution. If higher organisms primarily reproduce asexually, it implies that sexual reproduction, which involves more complex processes, may have developed at a later stage.
Statement IV further supports this hypothesis by highlighting the high occurrence of sexual reproduction in angiosperms and vertebrates. This observation aligns with the idea that more advanced organisms exhibit a greater prevalence of sexual reproduction.
Therefore, Option 3 makes the correct answer.
