I believe there is a mistake in your choices, because I don't see the correct choice here. The correct answer should be ABAB ABCB.
This is because in the first stanza, the first line A (son) rhymes with the third line A (shun), and the second line B (catch) rhymes with the fourth line B (Bandersnatch) - which makes the first stanza ABAB.
In the second stanza, the first line A doesn't rhyme with anything (hand), the second line B (sought) rhymes with the fourth line B (thought), and the third line C doesn't rhyme with anything - which makes the second stanza ABCB.
