Which sentence correctly uses the past perfect tense with ‘if only’ to express regret about the past?

Explanation

‘If only,’ when expressing regret about something that did not happen in the past, is followed by the past perfect tense, giving ‘If only I had studied harder.’ This differs from using ‘if only’ to express a wish about the present or future, which would instead use a different tense, such as the simple past for a present wish.
