Task: Answer the multiple choice question.
Question: Which compound exhibits a 4.739\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: C#CCNC(=O)C1=C[C@@H](c2ccc(C#C)cc2)C[C@@H](OCCCCO)O1
b: Cc1ccccc1NS(=O)(=O)c1cc(S(C)(=O)=O)ccc1Cl
c: CCOc1ccc(C(=O)C(C)OC(=O)c2nc(Cl)ccc2Cl)cc1
d: COCCn1c(NCc2ccco2)nc2c1c(=O)[nH]c(=O)n2C
e: COc1ccc(/C=N/NC(=O)c2ccc(NC(=O)c3cccc([N+](=O)[O-])c3)cc2)c(OC)c1
Answer: b. Cc1ccccc1NS(=O)(=O)c1cc(S(C)(=O)=O)ccc1Cl
