Fill in the blank with a suitable verb form:
The letter ________ by Rumi yet.
An action in a sentence can be represented in two ways, namely active and passive voice.
The passive voice always uses the past participle form of the main verb irrespective of any tense. Only the auxiliary verbs depend upon the sentence given in active voice.
The correct answer is D) Has not been written as 'yet' indicates present perfect tense.
Options A, B, and C are not correct as 'been' is not used, 'letter' is a singular noun, and the main verb is not used in its third form.
The letter has not been written by Rumi yet.
