A. Under the scheme the investors may be permitted to buy shares from foreign companies
B. Under the scheme the investors have been permitted to buy shares from foreign companies
C. Under the scheme the investors were permitted to buy shares from foreign companies
Feedback It is a simple present tense sentence because the first form of verb is given (active voice) to us. Its transformation to passive tone would be of the form ‘is / am / are + past participle form of the verb'. So, option (c) is correct.
D. Under the scheme the investors were permitted to buy shares from foreign companies
