What is the difference between mind and care? Why is not care the right answer?

Thanks in advance.

'If you don't mind' means 'if you have no objection', 'if it doesn't annoy you'.

'If you don't care' means 'if you don't worry', 'if you don't feel interested' and doesn't fit in the test sentence.
