The following sentence has been divided into parts. One of them may contain an error.
(1) It is raining / (2) when they played / (3) the cricket match last night. / (4) No error

Correct option is B

Option (b) contains an error.
The error is in part (1), "It is raining." The sentence describes an event that happened in the past ("last night"), so the verb tense should also be in the past. The correct sentence should be "It was raining when they played the cricket match last night."
Grammatical rule used:
· Tense consistency: When describing past events, all verbs should align in the past tense. Therefore, "It is raining" should be changed to "It was raining" to match the past event "played."
