Task: Answer the multiple choice question.
Query: Which drug exhibits a -8.762% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a CCN1CCN(C(=O)/C=C/c2ccc(C)o2)CC1
b O=C(NC(NC1CCS(=O)(=O)C1)C(Cl)(Cl)Cl)c1ccc(Br)cc1
c CC(C)(C)c1nnc(NC(=O)c2cc(-c3ccccc3)nc3ccccc23)s1
d O=C(CCCn1cnc([N+](=O)[O-])n1)Nc1ccc(F)c(Cl)c1
Answer: a. CCN1CCN(C(=O)/C=C/c2ccc(C)o2)CC1
