Task: Answer the multiple-choice question.
Query: Which drug exhibits a -0.278\% 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(Cn1nnc(-c2ccc(S(=O)(=O)N3CCCC3)cc2)n1)Nc1ccccc1-n1cccc1
b COCCNC(=O)C1CC(c2cccc(OC)c2)=NO1
c Cc1cccc(/C=C2\CCC(C3CCCC3)C2=O)c1
d O=C(Nc1ccc(N2CCN(C(=O)c3ccco3)CC2)c(Cl)c1)c1cccs1
Answer: b. COCCNC(=O)C1CC(c2cccc(OC)c2)=NO1
