The correct option is
C is organised
The notice is about an inter-school volleyball match to be held between Jasmine Public School and Pansy International School.
Option A: The verb, 'was organised' is in past tense. The notice cannot be about a match which was organised and held in the past and so is incorrect.
Option B: The verb, 'are organised' is incorrect as the verb, 'are' cannot be used with the third person singular noun, 'match'.
The correct verb is, 'is organised', in present tense. Hence, option C is correct.
Option D: The verb, 'has organised' is used after the subject of a sentence in active voice. However, the given sentence is in passive voice. Hence, this option is incorrect.
