Parts of the following sentence have been given as options. Select the option that contains an error.
He was playing cricket when I have walked past the stadium early in the morning.

Correct option is C

Option (c) contains the error.
Explanation: “have walked” is present perfect tense, which is incorrect here. The main sentence is in past continuous (“was playing”), so the action in the second clause should also be in simple past – “I walked”.
Correct sentence: He was playing cricket when I walked past the stadium early this morning.
Grammatical Rule Used:
✔ When two actions happen in the past, the longer action uses past continuous and the shorter one uses simple past.
�� Information Booster:
Past Continuous + When + Simple Past → He was sleeping when the doorbell rang.
