Task: Answer the multiple choice question.
Query: Which drug exhibits a 12.918\% 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) COc1ccc([N+](=O)[O-])cc1NS(=O)(=O)Cc1ccccc1
(b) CC1(C)CC(NC(=O)c2ccccc2Cl)CC(C)(C)N1.Cl
(c) CCO[C@H]1OC(C(=O)NCc2ccccc2)=C[C@@H](C)[C@@H]1CCCO
(d) CC(=O)N1CCN(C(=O)c2cc(S(=O)(=O)NCc3ccccc3)ccc2C)CC1
Answer: b. CC1(C)CC(NC(=O)c2ccccc2Cl)CC(C)(C)N1.Cl
