Question

Complete the following sentence by choosing the correct passive form from the given options:
Plants ________ by the gardener yesterday
(a) were watered (b) watered
(c) have watered (d) had been watered

Answer 1

Option a, 'were watered' is the correct passive form of the verb that is to be used in the sentence. It also clearly shows that 'plants' is the object of the sentence.

All the other options are incorrect because they would be logically and grammatically incorrect if used in the sentence.
