Task: Answer the multiple-choice question.
Question: Which compound exhibits a 15.985\% 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. CCOC(=O)CC(NC(=O)c1cccc2c1C(=O)N(Cc1cccnc1)C2)c1ccc(OCC)c(OC)c1
b. Cc1ccc(S(=O)(=O)N2CCN(C(=O)COc3ccc(C)nc3[N+](=O)[O-])CC2)c(C)c1
c. CCc1cc2c3c(c1)C1(C(=O)N3C(C)(C)C=C2C)C(C#N)=C(N)Oc2[nH]c(=O)[nH]c(=O)c21
d. O=Cc1cn(Cc2ccc(Br)cc2)c2ccccc12
e. Cc1cc([N+](=O)[O-])ccc1NC(=S)NC(=O)Cc1ccccc1
Answer: c. CCc1cc2c3c(c1)C1(C(=O)N3C(C)(C)C=C2C)C(C#N)=C(N)Oc2[nH]c(=O)[nH]c(=O)c21
