Task: Answer the multiple choice question.
Question: Which drug exhibits a 3.830\% 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) COc1ccc(S(=O)(=O)Nc2ccc(S(=O)(=O)N(C)C)cc2)cc1[N+](=O)[O-]
(b) CCn1c(SCC(=O)Nc2ccc(OC)cc2OC)nc2nc3c(cc2c1=O)COC(C)(C)C3
(c) CSc1ccc(S(=O)(=O)N(CC(=O)NCc2ccccn2)c2ccc(C)cc2)cc1
(d) COc1ccccc1S(=O)(=O)Cc1ccc(C(=O)NCCN2CCCC2)o1
Answer: a. COc1ccc(S(=O)(=O)Nc2ccc(S(=O)(=O)N(C)C)cc2)cc1[N+](=O)[O-]
