Identify the segment that contains a grammatical error. If there is no error, select ‘No error’.
Sorry I will be late as a flight/has been delayed due/to bad weather.

Correct option is D

The phrase “as a flight has been delayed” is unnatural. The correct structure should be “because a flight has been delayed” or “as my flight has been delayed”. The article “a” makes it vague.
Grammatical Rule Used:
Use of conjunctions – "as" can show cause, but it should be followed by a clear clause. Articles should agree with the noun being referenced. “A flight” suggests randomness; “my flight” is specific.
Explanation in Hindi:
“As a flight” कहना अस्पष्ट है। सही होगा – “because my flight” या “as my flight”. “a” article यहाँ उपयुक्त नहीं है।
Meanings of all options:
· (a) No error: Incorrect, because (d) has an error.
· (b) has been delayed due: Grammatically okay.
· (c) to bad weather: Prepositionally correct.
· (d) Sorry I will be late as a flight: Error in article and clause usage.
