I’m pretty sure this answer is the letter A.
But I’m pretty sure that that’s not correct but I remember taking this test and answering it like that
The sentence had repetitive words replaced with synonyms and pronouns. "but my father disliked..." is too much alike to "my father disliked" so it would get tedious and harder to read.
They replaced it with "but he hated ... " to get some variation.
