Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -0.587\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: O=C(Nc1cccnc1)c1cc(F)cc(F)c1
b: CCOc1cc(C(C#N)N2CCCCC2)ccc1OC
c: COc1cc(/C=C/C(=O)OCN2C(=O)c3ccccc3C2=O)ccc1OC(F)F
Answer: b. CCOc1cc(C(C#N)N2CCCCC2)ccc1OC
