Task: Answer the multiple choice question.
Question: Which drug exhibits a 5.169\% 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 additional words.
Options:
a O=C(COc1cccc(Cl)c1)Nc1ccc2c(c1)CCC2
b COc1cc(/C=C2\SC(=S)N(CCC(=O)Nc3ccccc3)C2=O)cc(OC)c1OC
c CC1(C)CC(NC(=O)c2cc(COc3cccc(C(F)(F)F)c3)on2)CCO1
d CP(=S)(Nn1cnnc1)Oc1ccccc1
Answer: b. COc1cc(/C=C2\SC(=S)N(CCC(=O)Nc3ccccc3)C2=O)cc(OC)c1OC
