Explanation:

This sentence does not have a redundancy problem. Something that is redundant is repeated. In option C, the redundancy problem is "postpone" and "until later". These mean the same thing. In option B the redundancy is "weekend" and "end". In option D, the redundancy is "square" and "shape". A square is a shape so this is repetitive.
