The following sentence has been split into four segments. Identify the segment that contains a grammatical error.
You will not invited / to any function / by them / if you don’t attend the marriage.

Correct option is B

The segment that contains a grammatical error is (b) "You will not invited." The corrected version should be "You will not be invited."
The verb phrase is missing the auxiliary verb "be" to form the correct passive voice structure necessary for this future negative construction.
Grammatical rule used: Formation of the passive voice in the future tense.
Example: You will not be admitted without a ticket.
