Answer 2

They have known each other for a month.

Explanation: In this sentence, we need to use the Present Perfect Simple or Continuous form of the verb "know" to indicate an action that started in the past and is still ongoing or has just been completed.

The correct form to use here is the Present Perfect Simple, which is formed by using the auxiliary verb "have" or "has" followed by the past participle of the main verb. In this case, the past participle of "know" is "known". Since the subject is "They", we use the plural form of the auxiliary verb "have".

Therefore, the correct sentence is: "They have known each other for a month."
