The correct option is A like
Here, 'like' is correct because it implies talking about things or people which people enjoy or feel positive about. Here, friends 'enjoy or feel positive about' playing tennis.
'Wants' is incorrect because it implies to have a desire or a wish for something.
'Can' is incorrect because it is used to say that it is possible for somebody/something to do something, or for something to happen. Moreover, it is grammatically incorrect.
'Likes' is incorrect due to subject-verb disagreement. Subject (friends) is plural, so plural verb (like) is correct.
