A Correct answer
Explanation

'Ago' is used to indicate time elapsed before the present moment ('I saw him two months ago'). 'Before' typically requires a reference point or event ('two years before that'), 'since' implies from a past time until now, and 'for' indicates duration. With simple past tense and a time reference from now, 'ago' is correct.
