peer review - Should I write a rebuttal for all for the reviewers or just the rejecting reviewers?

From a computer science conference, I have received 4 reviews. Two of the reviewers have accepted the article and have appreciated the work, while the other two have given "weak reject". The conference has asked us to submit a rebuttal within 3 days (seems a hard deadline; but it is okay).

My question is:

• Should I write the rebuttal for all the reviews? or


• Should I write the rebuttal for the comments on the weak-reject decisions?
