Task: Answer the multiple choice question.
Query: Which compound exhibits a -1.272\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a C=CCc1ccc(OCC(O)CN2CCC(Cc3ccccc3)CC2)c(OC)c1.Cl
b CCOc1cc(/C=C(\C#N)C(=O)NCC2CCCO2)ccc1O
c COc1ccccc1C1/C(=C(/O)c2ccccc2)C(=O)C(=O)N1CC(C)O
d N#Cc1ccccc1OCC(=O)Nc1nnc(C2CC2)s1
Answer: b. CCOc1cc(/C=C(\C#N)C(=O)NCC2CCCO2)ccc1O
