Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 8.478\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] O=C1NN(c2cccc(Br)c2)C(=O)/C1=C\c1ccc(N2CCOCC2)cc1
[b] COc1ccc(CNC(=O)CSc2nnc(C)s2)cc1OC
[c] O=C(CSc1nccc2ccccc12)N1CCN(c2ccccn2)CC1
[d] O=c1c2ccccc2nc(-c2ccccc2)n1/N=C/c1ccc([N+](=O)[O-])cc1
Answer: c. O=C(CSc1nccc2ccccc12)N1CCN(c2ccccn2)CC1
