Task: Answer the multiple choice question.
Query: Which drug exhibits a 26.544\% 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. O=S(=O)(Nc1c(F)cccc1F)c1ccc(Cl)nc1
b. COc1ccc(C(=O)Cn2cnc3ccccc3c2=O)c(OC)c1
c. Cc1ccc(-c2nc(NCc3ccco3)n(C(=O)c3ccco3)n2)cc1
d. O=C(Nc1ccccc1)c1ccc(NC(=O)C2CC2)cc1
e. CN(CC(=O)O)Cc1nc2ccccc2[nH]1.Cl
Answer: a. O=S(=O)(Nc1c(F)cccc1F)c1ccc(Cl)nc1
