Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 2.754\% 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(CC(=O)n2nc(-c3ccc(Cl)cc3)nc2NCc2ccco2)cc1
b: COC(=O)CSc1nnc(C)c(=O)[nH]1
c: CCOC(=O)C(Cc1ccccc1)C(=O)c1ccco1
Answer: b. COC(=O)CSc1nnc(C)c(=O)[nH]1
