Answer 1

The correct option is a) n(n-4).

Explanation:

Consider the provided information.

Let n represents the number of rows.

The number of seats in each row is 4 less than the number of rows.

This can be written as:
`n-4`

A theater has n rows of seats.

Therefore the total number of seats in the theater is:

`n(n-4)`

Hence, the correct option is a) n(n-4).
