Task: Answer the multiple choice question.
Query: Which compound exhibits a -2.115% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a. CCCCSCCCNC(=O)c1cn(CC)c2ccc(S(=O)(=O)N3CCOCC3)cc2c1=O
b. Cn1c(=O)c2c(SCCN3CCOCC3)nc(C3CCCC3)nc2n(C)c1=O
c. CN(c1ccc(C(=O)Nc2cccc([N+](=O)[O-])c2)cc1)S(C)(=O)=O
d. O=c1c2ccccc2nc(SCc2ccc([N+](=O)[O-])cc2)n1CCCO
Answer: b. Cn1c(=O)c2c(SCCN3CCOCC3)nc(C3CCCC3)nc2n(C)c1=O
