Task: Answer the multiple choice question.
Question: Which drug exhibits a 16.286\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a. CC1=C2C3OC(=O)C(C)[C@@H]3CC[C@](C)(O)C2C2C3C4C5(C12)[C@H]1OC(=O)[C@@H](C)C1CC[C@]4(C)O[C@]5(C)[C@@H]3O
b. CCOC(=O)c1oc2ccccc2c1NC(=O)CN1CCN(C)CC1
c. COc1ccc(NC(=O)CC2Oc3ccc(C)cc3NC2=O)cc1
d. C=C(C)CNC(=S)N/N=C(\C)c1ccc(OC)cc1
e. Cc1ccc(N/N=C/c2cccnc2)cc1.Cl
