Select the option that expresses the given sentence in active voice.

Rekha was very fascinated by the solitude offered by the hillside.

The solitude offered by the hillside fascinated Rekha very much.

The correct active voice of the given sentence is The solitude offered by the hillside fascinated Rekha very much.

The passive voice of the sentence is Rekha was very fascinated by the solitude offered by the hillside. This sentence is in the simple past tense, which is used to describe an action that happened in the past. The passive voice of the sentence is formed by putting the subject of the active sentence after the verb "to be" and the past participle of the main verb. In this case, the subject of the active sentence is "Rekha" and the main verb is "fascinate." The past participle of "fascinate" is "fascinated." So, the passive form of the sentence is Rekha was very fascinated by the solitude offered by the hillside.

The active voice of the sentence is formed by putting the subject of the passive sentence before the verb and removing the verb "to be." In this case, the subject of the passive sentence is "the solitude offered by the hillside" and the main verb is "fascinate." So, the active form of the sentence is The solitude offered by the hillside fascinated Rekha very much.

The other options are incorrect because:

• The solitude offered by the hillside was fascinating Rekha very much. is in the present progressive tense, while the original sentence is describing an action that happened in the past.
• The solitude was offering Rekha the hillside fascination very much. is grammatically incorrect. The word "fascination" is not a verb.
• The solitude was offered by the hillside fascinating Rekha very much. lacks the preposition "by."
