The correct answer is b. had saved, had bought, was holding, sounded.<br /><br />Explanation:<br />1. "had saved" - The action of saving money happened before another past action (buying the tickets), so the past perfect tense is used.<br />2. "had bought" - The action of buying the tickets happened before another past action (holding the tickets), so the past perfect tense is used.<br />3. "was holding" - The action of holding the tickets was ongoing at a specific time in the past, so the past continuous tense is used.<br />4. "sounded" - The action of the tickets sounding in his ears was a single, completed action in the past, so the past simple tense is used.
