Welcome to the forum.

I am not sure what your level of Spanish is nor what the full sentence is. I assume it includes 'problema' and the verb is 'preferir'

The construction you have used can be followed by indicative or subjunctive depending on the meaning of the sentence.

If you are new to Spanish your teacher will not give you an exercise involving the subjunctive mood.

If you type the verb into the front page of this site, it will give you its uses plus conjugations. Where it does not follow the standard pattern, it is in red.

Put in the conjugation you think is correct, then edit your question with any doubts you have eg is it present indicative or present subjunctive.

If this is not an exercise for a class but is you self teaching,make it clear.
