Answer 1

The correct option is B ii and iii

Diaphragms:

Diaphragms are barriers made up of rubber which are inserted into the female reproductive tract to cover the cervix during coitus.


They are introduced into the uterus:

Diaphragm is a cap, dome-like structure which is introduced in the vagina of a female to cover the cervix before coitus and not uterus.



They are placed to cover the cervical region:

Diaphragms are introduced in the vagina to cover the cervical region of the female reproductive tract to prevent the physical meeting of gametes (egg and sperm).

Thus, it is a correct statement about diaphragm.


They act as physical barriers for sperm entry:

Diaphragms prevent the entry of sperms as it covers the uterus and hence, prevents fertilisation.



They act as spermicidal agents:

Diaphragms are not spermicidal. They are the physical barriers that prevent the entry of sperms in the vagina.



Final answer: (c) ii and iii
