Select the correct passive form of the given sentence.

They will cancel the football tournament this year.

The football tournament will be cancelled this year.

The correct passive form of the given sentence is The football tournament will be cancelled this year.

The active voice is formed by putting the subject of the sentence before the verb and the past participle of the main verb. In this case, the subject of the sentence is "they" and the main verb is "cancel." The past participle of "cancel" is "cancelled." So, the active form of the sentence is "They will cancel the football tournament this year."

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 "the football tournament" and the main verb is "cancel." The past participle of "cancel" is "cancelled." So, the passive form of the sentence is "The football tournament will be cancelled this year."

The other options are incorrect because:

• The football tournament is being cancelled this year is in the present progressive tense, while the original sentence is in the simple future tense.
• The football tournament was cancelled this year is in the past tense, while the original sentence is in the simple future tense.
• The football tournament has been cancelled this year is in the present perfect tense, while the original sentence is in the simple future tense.
