Question

my father always pays....credit card fill in the blanks with the preposition

Answer 1

my father always pays by credit card.


I hope it will help u

Answer 2

Here the right preposition will be ‘by’.

Therefore the sentence comes as ‘My father always pays by credit card’.  

If you pay something that you are buying then you have to use to with pay.

But as you are paying via your credit card, you are paying your bills.

In these cases you have to use the preposition ‘by’ with pay.
