Task: Answer the multiple choice question.
Query: Which compound has a -5.420\% 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(NCc1ccc(F)cc1)C1CCCN1S(=O)(=O)c1cccc2nsnc12
b Cn1nc(CC(=O)N2CCN(c3ccccc3)CC2)c2ccccc2c1=O
c O=C1CCC(C(=O)Nc2cccc(Oc3ccccc3)c2)=NN1
d COC(=O)c1ccc(C(C(=O)NC2CCCCC2)N(Cc2ccccc2)C(=O)Cc2cccs2)cc1
Answer: b. Cn1nc(CC(=O)N2CCN(c3ccccc3)CC2)c2ccccc2c1=O
