Task: Answer the multiple choice question.
Query: Which compound exhibits a 2.971\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) COc1ccc(-c2c3c(nc4sc(C(=O)Nc5cc(C)on5)c(N)c24)CCC3)cc1
(b) COc1cc(CC(=O)OCC(=O)Nc2ccccc2C#N)cc(OC)c1OC
(c) O=C(Nc1nnc(-c2ccccc2Cl)o1)c1nc2ccccc2s1
Answer: c. O=C(Nc1nnc(-c2ccccc2Cl)o1)c1nc2ccccc2s1
