Answer 1

Hint:-An activity in a sentence can be spoken in an active and passive voice.
-The passive voice consistently utilizes the past participle type of the primary action word regardless of any tense.
-Just the auxiliary verb relies on the sentence given in the active voice.

Complete answer:
Active voice: Subject + Verb + Object
Passive voice: Object + Verb + Subject

You may have noticed that the verb structure changes when you change from active to passive voice. Presently verbs utilized are of two sorts: the primary and the helper verbs. Generally, an auxiliary verb is joined by the principle action word. The helper verb like be, do, or have shown the tense or state of mind of the verb. For instance, in the sentence "I have completed my cooking course in the Masterchef Hotel", completed is the principle verb and have is the helper verb.
Option B is right as the subject of the given sentence comes in the spot of the object (sums) and the other way around, a similar tense is utilized (present continuous tense), and the sentence is changed utilizing the fitting auxiliary verb 'are' as 'sums' is plural with 'being' as the past participle of the primary verb (do).

The correct answer is Option B.

Note:As a thumb rule, Passive voice sentences consistently take the third type of the verb additionally called the past participle type of the action word. Example - sing, sang, sung.
Sung is the third type of verb.
So the use of the main verb is really easy to change over. It's the helper action word that we need to see further.
