Task: Answer the multiple choice question.
Query: Which compound has a -47.285\% 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=CCn1c(=O)c2c(nc3n2CCCN3CCc2ccc(OC)c(OC)c2)n(C)c1=O
b. Cc1ccc(S(=O)(=O)N2C(=O)CCC2C(=O)N2CCCCC2)cc1
c. O=C(c1ccc(NC2=NC3CS(=O)(=O)CC3S2)cc1)N1CCN(c2ccc(F)cc2)CC1
d. CC(=O)Nc1ccccc1C(=O)C(=O)Nc1ccc(Cl)cc1
Answer: a. C=CCn1c(=O)c2c(nc3n2CCCN3CCc2ccc(OC)c(OC)c2)n(C)c1=O
