Question

Which of the options given below is the correct passive form of the following sentence ? 
"The Bhagvad Gita presents a balanced philosophy of life."

Accepted Answer

Option 1 is the correct passive form because it accurately reflects the tense and meaning of the original active sentence.

Here's why:

*   **Original Sentence (Active):** "The Bhagvad Gita presents a balanced philosophy of life." This sentence is in the simple present tense.

*   **Passive Voice Formation:** To convert an active sentence in the simple present tense to passive voice, we use the following structure:

*   Object of the active sentence becomes the subject of the passive sentence.
    *   The verb "to be" (is, am, are) is used in the present tense, agreeing with the new subject.
    *   The past participle of the main verb is used.
    *   The subject of the active sentence becomes the object of the preposition "by" (optional).

*   **Option 1 (Passive):** "A balanced philosophy of life is presented by the Bhagvad Gita." This option correctly follows the structure for converting the simple present active sentence to passive. "A balanced philosophy of life" (the object of the active sentence) becomes the subject. "Is" (the present tense form of "to be") is used. "Presented" is the past participle of "present." "The Bhagvad Gita" (the subject of the active sentence) becomes the object of "by."

**Why the other options are incorrect:**

*   **Option 2: "A balanced philosophy of life has been presented by the Bhagvad Gita."** This option uses the present perfect tense ("has been presented"). The original sentence is in the simple present tense, so changing the tense is incorrect.

*   **Option 3: "The Bhagvad Gita has presented a balanced philosophy of life."** This option is in the active voice and the present perfect tense. It doesn't convert the original sentence to passive voice at all.

*   **Option 4: "A balanced philosophy of life was presented by the Bhagvad Gita."** This option uses the simple past tense ("was presented"). The original sentence is in the simple present tense, so changing the tense is incorrect.
