Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -1.176\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a.) COc1ccc(NC(=O)c2ccccc2N2C(=O)C3C4C=CC(C5CC45)C3C2=O)c(OC)c1
b.) CCOC(=O)N1CCN(C(=O)c2csc3c2CCCCC3)CC1
c.) O=C(CN1CCN(S(=O)(=O)c2cccc(Br)c2)CC1)N1CCCCC1
d.) Cc1cc(C)nc(NS(=O)(=O)c2ccc(N=Cc3c(C)[nH]n(-c4ccccc4)c3=O)cc2)n1
