Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -6.457\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] CC(=O)CC(C)(C)S(=O)(=O)c1ccc(NC(C)=O)cc1
[b] Cc1cc(OCC(=O)Nc2ccc(CN3CCOCC3)cc2)ccc1Cl
[c] CCOC(=O)C(=O)Nc1ccc(OCc2ccccc2)cc1
[d] Cc1cc(N2CCN(C)CC2)nc2ccc(NC(=O)CCC(=O)NCCC3=CCCCC3)cc12
Answer: b. Cc1cc(OCC(=O)Nc2ccc(CN3CCOCC3)cc2)ccc1Cl
