Task: Answer the multiple choice question.
Question: Which drug exhibits a -13.051% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: CCn1cc(CCC(=O)NCc2ccccc2OC)c2ccccc21
b: S=C(Nc1ccccc1)N1CCn2c(nc3ccccc32)C1
c: CCN1CCN(CCOc2ccccc2OCc2ccccc2)CC1.O=C(O)C(=O)O
d: CCCn1nnnc1COc1ccc(C(N)=O)cc1
Answer: b. S=C(Nc1ccccc1)N1CCn2c(nc3ccccc32)C1
