Which of the following sentences is correct?

The correct answer is Option (4) → The shopkeeper accused the new helper of taking money from the cash box.

“Accuse” is followed by “of”:

• We accuse a person of doing something wrong.
• “Of” is a preposition, so the verb after it takes the -ing form: “of taking”.

Why the Other Options are Incorrect?

Option 1: The shopkeeper accused the new helper for taking money from the cash box. — Incorrect. “Accuse” takes “of”, not “for”.

Option 2: The shopkeeper accused the new helper with taking money from the cash box. — Incorrect. “With” goes with “charged”, as in “charged with theft”. “Accused” takes “of”.

Option 3: The shopkeeper accused the new helper to take money from the cash box. — Incorrect. “Accuse” is not followed by “to” + verb. It takes “of” + the -ing form.
