Read the notice given and fill in the blank [3] with the most appropriate option.
A notice is a printed or written announcement for informing a group of people about an event.
C. written is correct as the information in a notice is always written in the passive voice. The active voice of the sentence uses the simple present tense. Moreover, the presence of 'be' before it calls for a verb in past participle form. Therefore 'written' must be used here.
The other options are wrong as they cannot be used as they are in active voice and Notice is not written in the active voice.
