Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -6.145\% 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 additional words.
Options:
(a) O=C(Cc1nc2ccccc2[nH]1)c1cccc([N+](=O)[O-])c1
(b) O=C(Nc1cccc2ccccc12)OC1C=CS(=O)(=O)C1
(c) O=C(CSc1ncn(-c2ccccc2)n1)Nc1ccc(Br)cn1
(d) CCOC(=O)C(C(=O)OCC)C(NS(=O)(=O)c1ccccc1)(C(=O)OC)C(F)(F)F
Answer: c. O=C(CSc1ncn(-c2ccccc2)n1)Nc1ccc(Br)cn1
