The following sentence has been split into four segments. Identify the segment that contains an error.

I had seen / her with her mother / in the cinema hall / yesterday.

The correct answer is I had seen.

Explanation:

The sentence contains an error in the segment "I had seen".

In English grammar, when a specific time expression in the past is mentioned (such as yesterday, last night, in 1999, two days ago), we use the Simple Past Tense instead of the Past Perfect Tense.

The Past Perfect Tense (had + past participle) is used to denote an action completed before another past action. Since there is only a single action tied to a specific past time marker ("yesterday"), the simple past verb "saw" should be used instead of "had seen".

Corrected Sentence:

"I saw her with her mother in the cinema hall yesterday."
