Task: Answer the multiple choice question.
Query: Which compound has a 10.294\% human ether-à-go-go related gene (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. COc1ccc(-c2cc3nc(C4CCN(C(=O)OC(C)(C)C)CC4)c(C(=O)O)cn3n2)cc1
b. O=C(Nc1ccc2nccnc2c1)Nc1ccccc1Cl
c. CCOc1ccc(NCc2nnc(SCc3ccccc3Cl)n2-c2ccccc2)cc1
Answer: b. O=C(Nc1ccc2nccnc2c1)Nc1ccccc1Cl
