For this case we can translate the sentence given as:
My father__________ watching the game on television.
The sentence refers to a third person masculine and singular.
We conjugate the verb "preferir" indicatively in imperfect preterite (Verb tense that expresses a past action while it is taking place).
yo prefería
tú preferías
él prefería
nosotros preferíamos
vosotros preferíais
ellos preferían
So, the correct way is "él prefería""
