Task: Answer the multiple-choice question.
Question: Which drug exhibits a 4.357\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a.) CCOc1ccc(CN(C)C(=O)c2cc3ccccc3o2)cc1OC
b.) COc1ccccc1NC(=O)N(C1CCCC1)C1CCN(C(C)=O)CC1
c.) O=C(Nc1ccc(F)cc1)N1CCCN(c2nccc(C(F)(F)F)n2)CC1
Answer: a. CCOc1ccc(CN(C)C(=O)c2cc3ccccc3o2)cc1OC
