The correct answer is: Amphibians and algae
When fertilization occurs outside the body of the organism, this type of gametic fusion is called external fertilization or external syngamy. The external medium such as water is required for this type of fertilization. Thus, in most aquatic organisms such as a majority of algae, fishes and amphibians, external fertilization occurs.
