Select the option that correctly infers the meaning of the given sentence.

If Ravi had studied hard, he would have cleared the test.

The correct answer is 'Option 2.'

Key Points

• The sentence is a conditional type 3 sentence, which expresses a situation that did not happen in the past.
• It indicates that Ravi did not study hard, and as a result, he did not clear the test.
• The structure "If...had + past participle, would have + past participle" implies a hypothetical situation in the past and its possible outcome.
• In this case, the hypothetical situation is Ravi studying hard, and the possible outcome is him clearing the test.
• Hence, the correct answer is 'Ravi did not study well, so he failed in the test.'

Therefore, the correct answer is 'Option 2.'

Additional Information

• Option 3: Ravi studied well, so he cleared the test. (Incorrect) - This option contradicts the conditional structure and the meaning conveyed by the original sentence. 
• Option 4: Ravi did not study well, but he cleared the test. (Incorrect) - This option contradicts the original sentence.
