Solution
The correct option is D Teratogens
Teratogens can cause foetal abnormalities if given to a pregnant woman. Placenta does not act as barrier due to which the drugs can pass to the foetus. These drugs can affect the foetus at either of the following stages, fertilisation and implantation or organogenesis or growth and development. The capacity of drugs to induce foetal abnormalities when given to pregnant women is called teratogenicity. For example, synthetic teratogen thalidomide can cause phocomelia (seal like limbs) in babies. So, the correct answer is 'Teratogens'.
