The following sentence is divided into four parts and are given in the alternatives A, B, C, and D. Select that alternative which contains that part of the sentence which has an error. Selecting the part with the error is the answer.
Each wall must be painted by white paint.
Show answer & explanation
Correct answer: C
Explanation
The error lies in the choice of preposition.
In English, we use the preposition "with" when referring to the instrument, tool, or material used to perform an action. We use "by" when referring to the person or agent performing the action.
Since "white paint" is the material being used, the preposition should be "with."
