Choose the appropriate word to replace the underlined word for formal correspondence in the given sentence:

Kindly forward the emails quickly.

(A) Promptly
(B) Superfast
(C) Request
(D) Elapsed

Choose the correct answer from the options given below:

(A) Only

The correct answer is Option (1) → (A) Only

Promptly means done or happening without delay, which is a formal way to request swift action.

Superfast is informal and overly exaggerated.

Request is not a replacement for "forward" and doesn't convey the action of sending something on.

Elapsed means "passed" and doesn't fit the context of requesting speed.

Therefore, only option (A), "promptly," provides a formal and suitable replacement for "quickly" in this context.
