Continuous taking of some drugs foregoing the pregnancy increase the risk of giving birth to a child with genetic defects. What is this effect called?

Answer options

1. Embryotoxic effect
2. Blastomogenic effect
3. Teratogenic effect
4. Fetotoxical effect
5. Mutagenic effect

Explanation

This can't be a mutagenic effect but rather a teratogenic effect due to the following reason. A teratogen is an agent that can disturb the development of the embryo or fetus. Teratogens halt the pregnancy or produce a congenital malformation (a birth defect). Classes of teratogens include radiation, maternal infections, chemicals, and drugs. Whereas a mutagen is a physical or chemical agent that changes the genetic material, usually DNA, of an organism and thus increases the frequency of mutations.
