Task: Answer the multiple choice question.
Query: Which compound exhibits a -4.711\% 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.

a: COc1ccc(CC(=O)N/N=C/c2ccc(-c3ccc(F)cc3)o2)cc1OC
b: CCOC(=O)c1nc(Nc2ccc(C)cc2)c2ccccc2n1
c: COc1ccc(CCn2c(=N)c(C(=O)NC3CCCC3)cc3c(=O)n4cccc(C)c4nc32)cc1
Answer: b. CCOC(=O)c1nc(Nc2ccc(C)cc2)c2ccccc2n1
