Select the correct passive form of the given sentence.
The peon did not ring the bell on time.

Rule: To convert a sentence into passive voice, we follow this pattern:Subject (in active) + auxiliary verb (do/does/did) + not + verb (base form) + object.In the passive voice, the object becomes the subject, and the verb is changed to the appropriate form (usually the past participle), with the auxiliary verb "was" or "were" added based on the tense.
The active sentence "The peon did not ring the bell on time" is in the past simple negative tense.
The passive voice form will therefore be: The bell was not rung (past simple passive form).
"The bell had not been rung" is past perfect tense, which is incorrect here.
"The bell was not being rung" refers to an ongoing action in the past, which doesn’t match the context.
"The bell is not rung" is in the present tense, which is not suitable for the past action in the original sentence.
