Task: Answer the multiple choice question.
Question: Which compound has a 19.196\% 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. Cc1[nH]n(-c2ccccc2)c(=O)c1C(c1ccc([N+](=O)[O-])cc1)c1c(C)[nH]n(-c2ccccc2)c1=O
b. CC1=C(C(=O)Nc2ccccc2C(=O)N2CCC(C)CC2)SCCO1
c. COc1ccc(N/C=C\C(=O)c2ccc(C)cc2)cc1OC
d. COc1cc(OC)cc(C(=O)NC(=S)Nc2ccc(NC(=O)c3ccco3)cc2)c1
Answer: c. COc1ccc(N/C=C\C(=O)c2ccc(C)cc2)cc1OC
