4 October 2022
Mr. Aman Mittal
Director
Softel Technologies, Delhi

Dear Sir
This is with reference to your earlier letter.

i. Sender's address ii. Subject line

The correct answer is Option (2) → i. Sender's address ii. Subject line

In a formal letter, the sender’s address is written at the top before the date, which corresponds to blank (i). The details “Mr. Aman Mittal, Director, Softel Technologies, Delhi” clearly represent the receiver’s address, which is already given. After the receiver’s address, a subject line is written before the salutation “Dear Sir,” which corresponds to blank (ii). Hence, the correct answer is Option (2). 

• Option 1: A "Subscription" (like "Yours faithfully") appears at the end of the letter, not at the top. A "Salutation" is already present in the draft as "Dear Sir."

• Option 3 & 4: The "Receiver's Address" is already provided in the text (Mr. Aman Mittal...). Therefore, blank (i) at the very top must be the Sender's Address.
