Task: Answer the multiple choice question.
Question: Which compound exhibits a -4.683\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a.) Cc1nc2c(cc1C(=O)N/N=C/c1ccc([N+](=O)[O-])cc1)c(=O)n(C)c(=O)n2C
b.) CCOC(=O)N1CCC(NS(=O)(=O)c2cc(C(=O)OC)n(C)c2)CC1
c.) O=C(NCC1CCCO1)c1cc(S(=O)(=O)Nc2ccc(Br)cc2)ccc1Cl
d.) O=C(N[C@@H](Cc1ccccc1)C(=O)OCc1ccccc1)c1nc[nH]c1C(=O)NC1CC[NH2+]CC1.[Cl-]
e.) O=C(c1cnn(Cc2ccccc2)c1)N1CCN(S(=O)(=O)/C=C/c2ccccc2)CC1
