Task: Answer the multiple choice question.
Query: Which drug exhibits a 18.256\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] C=CCn1c(Sc2nc(C)cs2)nc2c1c(=O)[nH]c(=O)n2C
[b] CCn1cc(C(=O)NCc2ccccc2OC)c(=O)c2ccc(C)nc21
[c] OCCCn1c(-c2ccccc2)n[nH]c1=S
Answer: b. CCn1cc(C(=O)NCc2ccccc2OC)c(=O)c2ccc(C)nc21
