Task: Answer the multiple choice question.
Query: Which drug has a 19.796% 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 other words.
Options:
a: CCOC(=O)c1nnc(-c2ccccc2)o1
b: CCOc1ccc(-n2c(SC)nc3c(c2=O)SCC3)cc1
c: CC(C)(C)c1nc(SCC(=O)NCc2ccco2)c2ccccc2n1
d: CCOC(=O)c1nc(-c2ccccc2)oc1N(C)C
Answer: b. CCOc1ccc(-n2c(SC)nc3c(c2=O)SCC3)cc1
