Answer 2

Answer:

(d) Fertilization that takes place outside the female body is called external fertilization. This is observed in frogs, fish and starfish.

So, the answer is all of the above.

Explanation:

• External fertilization takes place in frogs.
• Most species of starfish releases their eggs and sperm directly into the water, so fertilization is external.
• The starfish is an echinoderm, and it fertilises itself. The eggs of the majority of starfish species are released directly into the water. The male starfish then spits sperm onto the discharged eggs, fertilising them and forming zygotes.
