The branch of science dealing with the study of congenitally deformed fetus is called as
(A) Teratology
(B) Gerontology
(C) Nidology
(D) None of the above

Answer 1

Hint: Science is defined as the organized study of the knowledge about the living organisms. In this, many fields or branches are classified based on different topics. In the branch of biology given in the options, teratology and the gerontology deals with the human and the plants developmental changes and the nidology deals with the birds.

Complete answer:
(A) Teratology:
Teratology is defined as the branch of biology that deals with the study of the abnormalities in the physiological development of the fetus. It mainly involves the study of the congenitally abnormalities of the human before birth including puberty.

(B) Gerontology:
It is defined as the science that deals with aging. It includes the social, cultural, cognitive, and physiological and the biological aspects with respect to aging.

(C) Nidology:

The fetus is the organism inside the mother’s womb, which after the delivery is called a baby. It gets all its nutrients and the oxygen from the mother by the placenta or the umbilical card and disposes all its waste into the mother’s body, there it is excreted.

Hence, the correct answer is option (C)

Note: In the branch of teratology, the fetus abnormalities at the time of development of the womb and its deformities in the physiological development is studied. It also involves the study of the plants. Teratogens are the toxic substances that cause defects in birth.
