Answer 1

The correct option is A

i).➡ a., ii).➡ d., iii).➡ b., iv). ➡ d, v). ➡ e.

In reference; parts of the ear with functions :

i. Pinna a. Collects Vibrations in the air

ii. Cochlea d. Translates sound to nerve impulses

iii. Meatus b. Region between Pinna and ear drum

iv. Tympanic c. Transfers vibrations to ear ossicles

membrane

v. Eustachian tube e. Equalises pressure between the inner

outer ear

Therefore, the correct option is A. – i).➡ a., ii).➡ d., iii).➡ b., iv). ➡ c, v). ➡ e.
