Change the following sentence in to Active Voice. Choose the appropriate answer from the options given below

She is known to him.

He knows her.

The most appropriate option to change the passive voice sentence "She is known to him" into active voice is:

He knows her.

Here's why the other options are not ideal:

• He is knowing her: This is grammatically incorrect. The present continuous tense ("is knowing") is not appropriate in this context.
• He knew her: This might be correct depending on the intended meaning. If the speaker wants to say that he knew her in the past but might not anymore, this could be a valid option. However, the original sentence suggests an ongoing state of being known, making present tense more likely.
• He knows she: This is grammatically incorrect because the direct object (her) needs to be placed after the verb in active voice.

Therefore, the simplest and most accurate way to convert the passive voice sentence into active voice while preserving the original meaning is "He knows her."
