Answer:

Explanation:

Only cats are capable of internal fertilization from the given choices above.

Internal fertilization is the fusion of gametes within an organism. This process occurs during sexual reproduction within the female.

• Toads and fishes exhibit external fertilization.
• External fertilization occurs where the male sperm externally fertilizes the eggs of the female.
• This usually takes place in a moist or wet place especially water bodies. The liquid medium will transport the sperm to the egg.

In cats, the female specie takes in reproductive cells from the male during coitus and it fertilizes the her eggs to produce a zygote.
