Is this sentence This is to be handled by you grammatically correct?

Answer 1

Short answer : Yes and not impolite at all, as suggested below.

This is to be handled by you grammatically correct? requires inverted commas to be correct. It should be written as:

"Is this sentence "This is to be handled by you." grammatically correct?"

The sentence is correct but not very polite; it would be simpler to say "You are to handle this"
