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

I was taught by Shyam how to drive.

Shyam taught me how to drive.

The correct active voice form of the sentence "I was taught by Shyam how to drive" is Shyam taught me how to drive.

The passive voice of the sentence is "I was taught by Shyam how to drive." 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 "I" and the main verb is "teach." The past participle of "teach" is "taught." So, the passive form of the sentence is "I was taught by Shyam how to drive."

The active voice of the sentence is formed by putting the subject of the passive sentence before the verb and removing the word "by." In this case, the subject of the passive sentence is "Shyam," and the verb is "teach." So, the active form of the sentence is "Shyam taught me how to drive."

The other options are incorrect because:

• Shyam is teaching me how to drive. This sentence is in the present progressive tense, which is used to describe an action that is happening now but is not finished. However, the action of teaching you how to drive happened in the past.
• Shyam has taught me how to drive. This sentence is in the present perfect tense, which is used to describe an action that has happened in the past and is still relevant to the present. However, the action of teaching you how to drive is not happening now.
• I taught Shyam how to drive. This sentence is the opposite of the passive sentence, and is therefore incorrect.
