Correct option 3

The error lies in part R of the sentence. Hence, correct answer is option 3.

In the above sentence, the error lies in usage of preposition. The subject is talking about a specific line of action, since there is no mention of time or no establishment of a connection between two places, 'at' is the incorrect preposition.

'For' is the preposition that has to be used as it indicates, a definite purpose as to why the subject has to follow a line of action or thought.

Correct sentence:

My grandmother has invited you for dinner tonight at her apartment.
