Answer:
The correct answer is D. Clear.
Explanation:
If you put a preposition at the end of a sentence, it makes it less formal and it is not entirely grammatically correct. You should avoid placing prepositions at the end of sentences if you are trying to sound more formal or educated.
However, prepositions at the end of a sentence make it less awkward and more clear to understand - take a look at these examples:
- With whom are you going? - preposition at the beginning of the sentence, makes it sound very formal and slightly awkward, but grammatically correct.
- Who are you going with? - preposition at the end of the sentence, makes it sound informal and clear, but grammatically incorrect.
