The correct answer is OPTION 4 -- B and D only
The sentences showing the correct use of a preposition are:
B. "After lunch at a roadside eatery, they went to watch a movie."
- The preposition "After" is used correctly in this sentence.
D. "The missing truck was traced to its owner in Shillong last month."
- The preposition "to" is used correctly in this sentence.
Therefore, the correct answer is: B and D only
In sentences A and C, there are preposition errors:
- In sentence A, "trace about" is not the correct usage. It should be something like "trace the car" or "trace the whereabouts of the car."
- In sentence C, "noise above the downstairs" and "prevented him to come" is incorrect. It should be "noise from the downstairs prevented him from coming."
