Task: Answer the multiple-choice question.
Query: Which drug exhibits a 9.306\% 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) CCOC(=O)N1CCN(C(=O)C(C)NC(=O)c2ccco2)CC1
(b) COc1ccc(CC(=O)N(C)C2CCCCC2)cc1S(=O)(=O)N1CCOCC1
(c) CCOC(=O)/C=C/C(=O)Nc1ccc(S(=O)(=O)Nc2cc(C)on2)cc1
(d) COCCN=C1NN=C(c2ccc(C)c([N+](=O)[O-])c2)CS1
Answer: d. COCCN=C1NN=C(c2ccc(C)c([N+](=O)[O-])c2)CS1
