Select the correct passive form of the given sentence.

How can I forget your generosity?

How can your generosity be forgotten by me?

The correct passive form of the given sentence is How can your generosity be forgotten by me?

The original sentence is in the active voice, with the subject "I" and the verb "forget." The passive voice is formed by putting the subject of the active sentence after the verb "to be" and the past participle of the main verb. In this case, the subject of the active sentence is "your generosity" and the main verb is "forget." The past participle of "forget" is "forgotten." So, the passive form of the sentence is How can your generosity be forgotten by me?

The other options are incorrect because:

• How can your generosity be forgot by me? is grammatically incorrect. The past participle of "forget" is "forgotten," not "forgot."
• How your generosity can be forgot by me? is grammatically incorrect. The word "your" should be "yours" in this context.
• How has your generosity been forgotten by me? is in the past perfect tense, while the original sentence is in the present tense.
