Select the correct tense: I had seen him earlier.

Correct answer: Past perfect.

Explanation: The sentence uses 'had' + past participle (had seen), which is the form of the past perfect tense.

• Structure: had + past participle (e.g., had seen).

• Meaning: indicates an action completed before another past time or event.

• Other tenses: Past continuous uses was/were + verb-ing; past perfect continuous uses had been + verb-ing; future perfect uses will have + past participle. None of these match the form had + past participle used in the sentence.
