The correct option is A Vicky said that he helped him become focused and disciplined which still helps him even today.
‘Vicky said that he helped him become focused and disciplined which still helps him even today.’, is the correct answer as it changes the pronoun from ‘me’ to ‘him’ in reported speech, and the tense remains unchanged because the information, i.e, 'Mr. Neeraj helping Vicky become focused and disciplined' still remains true at the time of reporting.
