Problem statement: Answer the MCQ question.
Query: Which drug exhibits a 1.634% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: CCN1C(C(=O)c2ccccc2)=C(Nc2ccccc2C)c2ccccc2S1(=O)=O
b: COc1cccc(CNS(=O)(=O)c2c(C(=O)N3CCCCCC3)c(C)n(C)c2C)c1
c: Cc1cc(OCC(=O)OCC(=O)N2CCc3ccccc3C2)ccc1Cl
d: O=[N+]([O-])c1ccc(Sc2ccccc2Cl)nc1
e: CCOc1ccc(-n2c(SCC(=O)Nc3cc(OC)c([N+](=O)[O-])cc3C)nc3ccccc32)cc1
Answer: d. O=[N+]([O-])c1ccc(Sc2ccccc2Cl)nc1
