Correct option is B
Option (b) contains an error.
The segment "he is coming" is incorrect in this sentence because the reported speech should use the past tense to match the reporting verb "said" in the past tense.
The correct form should be "he was coming" to align with the past tense of the reporting verb "said."
Grammatical rule used: When reporting speech or thoughts using a reporting verb in the past tense, the verbs in the reported speech should generally be shifted to the past tense. This is known as "backshifting" in reported speech.
Example:
Direct speech: "I am coming from my village," said Binay.
Reported speech: Binay said that he was coming from his village.
In this case, the present continuous "is coming" needs to be changed to the past continuous "was coming" to maintain proper grammatical structure in reported speech.
