Answer 2

Frogs do not belong to the group based on their mode of reproduction. (Option A)

• Frogs are well-known for their ability to lay eggs. The most prevalent process is fertilization, in which the female releases her eggs into the water from her body. The male then discharges his sperm to fertilize the eggs.
• Hydra reproduces both sexually or asexually through budding and gamete production. Hydra regenerates at a high rate.
• Some aquatic planarians may reproduce sexually as well as asexually.
• Sea anemones may reproduce both sexually and asexually. The depth at which they reside in the water is determined by their reproduction style; the deeper they are, the more sexual reproduction they have, and the shallower they are, the more asexual reproduction they have.
• Given the above-mentioned form of reproduction, we may conclude that a frog is the odd one out here, since it can only reproduce sexually, whilst the other can reproduce both sexually and asexually.
