Fill in the blank with the most appropriate word.
A queue of people were waiting _____ the last bus.

• A. on
• B. at
• C. of
• D. for

Answer 1

Answer: (D)

for

Option D is the correct answer because 'for' is used to show a reason or cause.

Options A, B and C are incorrect because 'on' is used to indicate the surface of something, 'at' is used to indicate a specific time or location and 'of' is used to mean belonging to someone or something.
