Choose the correct sequence of the parts of a formal letter.

P. Subject
Q. Receiver's post and address
R. Salutation
S. Sender's address
T. Date

S, T, Q, P, R

The correct answer is Option (3) - S, T, Q, P, R

1. S (Sender's Address) → The letter starts with the sender's address.
2. T (Date) → The date follows the sender’s address.
3. Q (Receiver's Post and Address) → The recipient’s designation and address come next.
4. P (Subject) → The subject line states the purpose of the letter in a concise manner.
5. R (Salutation) → The letter formally addresses the recipient.

Thus, the correct sequence is:
✔ S (Sender's Address) → T (Date) → Q (Receiver's Post and Address) → P (Subject) → R (Salutation)
