Question

Fill in the blank with the most appropriate word.
He was occupied _____doing his homework.

• A. on
• B. in
• C. at
• D. by

Answer 1

Answer: (B)

in

Option B is the correct answer because 'in' is used to mean involved in something; taking part in something.

Options A, C and D are incorrect because 'on' is used to express a surface of something or place or location, 'at' is used to point out a specific time or a specific place and 'by' is used to indicate proximity or agency.
