Please help me with this question.

[siruss]

This question is from an English test called "TEPS".
I don't have the answer key to it.
I guess (d) despite is not the answer because despite is not a conjuction.
But I have no idea what to choose beween (a), (b), and (c).
I guess (a) now that is quite possible to be an answer, but I'm not sure.
Please help me.
Thank you for your help in advance.

Question.
A: I actually like Jack's hair ______ he had it dyed pink.
B: You're pulling my leg, aren't you?

a) now that
b) in case
c) what if
d) despite

I'm not a teacher, but what comes the most naturally to me is:

A: I actually like Jack's hair _now that_ he had it dyed pink
B: You're pulling my leg, aren't you?

To me, none of the other choices "feel right" in the sentence as given. I realize that this sort of answer, based as it is on the intuition of a native speaker, may sound pretty nebulous, so a partial explanation follows.

The phrase "in case" is usually used to mean "in the event that." For example, "He took an umbrella _in case_ it rained." But that sense doesn't look like it's present in the exchange as given, so (B) can be eliminated.

The phrase "what if" is usually used as part of a question. Since the exchange as given does not include a question, (C) can also be eliminated.

And for "despite" to work in the exchange, it would need to be followed by "the fact that" as in "I like Jack's hair despite the fact that he had it dyed pink."

Thank you for you kind reply.
I appreciate it.

I suspect there's a typo (a typing error) here. Had should be has:

A: I actually like Jack's hair ______ he has it dyed pink.
B: You're puling my leg, aren't you?

a) now that
b) in case
c) what if
d) despite
