Answer 1

The Correct Option is C

Step 1: Identify the verb phrase. The sentence uses the expression \[ \boxed{\text{dealt with}} \] which is a fixed verb-preposition combination.

Step 2: Recall the usage. The phrase deal with means
• to handle,
• to manage, or
• to resolve a problem or situation. Since the complaint was handled promptly, the correct preposition is with.

Step 3: Analyse the options.
• (A) about -- Incorrect. "Deal about" is not a correct expression.
• (B) on -- Incorrect. It does not form the required phrasal verb.
• (C) with -- Correct. "Deal with" means to handle or resolve.
• (D) over -- Incorrect. It does not fit the context.

Step 4: Final conclusion. \[ \boxed{\text{The complaint was dealt with promptly.}} \] Hence, the correct option is \(\boxed{(C)}\).
