Task: Answer the MCQ question.
Question: Which compound has a 19.608\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a CCOc1cc(Br)cc(/C=C2\SC(=Nc3ccccc3)NC2=O)c1O
b O=C(Nc1cccc([N+](=O)[O-])c1)C1CC(=O)N(C2CCCCC2)C1
c COc1cc(C2OC(c3cc(OC)c(OC)c(OC)c3)C(C)C2C)cc(OC)c1OC
d CN(CCC#N)C(=O)CC1(Cc2ccccc2)CCOC(C)(C)C1
e O=C(Nc1ccccc1-c1ccccc1)c1ccc(NC(=O)c2ccco2)cc1
Answer: a. CCOc1cc(Br)cc(/C=C2\SC(=Nc3ccccc3)NC2=O)c1O
