Task: Answer the multiple choice question.
Question: Which compound has a 17.938\% 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: CCOP(=S)(OCC)C(O)CCCCCn1c(=O)c(F)cn(C2CCCO2)c1=O
b: COc1ccc(CCn2c(O)c(C=Nc3ccc(NC(C)=O)cc3)c(=O)[nH]c2=O)cc1OC
c: COc1ccc(Cl)cc1S(=O)(=O)NC(C)C(=O)NCCCn1ccnc1
d: CC(=O)NN1C(=O)/C(=C/c2ccc(Br)o2)SC1=S
Answer: b. COc1ccc(CCn2c(O)c(C=Nc3ccc(NC(C)=O)cc3)c(=O)[nH]c2=O)cc1OC
