The simple past tense of the verb ‘answer’ is ‘answered’.
To explain further, in English, the simple past tense is used to indicate that an action was completed at a specific time in the past. For example, in the sentence ‘I answered the question yesterday,’ the action of answering was completed in the past. In regular verbs like ‘answer,’ we typically form the simple past by adding ‘ed’ to the base form of the verb.
