What is the correct past tense form to complete the sentence: 'Her father _____ yesterday'?

Explanation

The correct past tense form of the verb 'to die' used for a specific time in the past is 'died'. 'Dead' is an adjective, 'has died' is present perfect tense which is not typically used with a specific past time like 'yesterday', 'was died' is grammatically incorrect, and 'had died' is past perfect tense which requires another past reference point.
