Task: Answer the multiple-choice question.
Question: Which drug exhibits a 4.286% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a. Cc1cccc(Cn2c(NCC(C)O)nc3c2c(=O)n(C)c(=O)n3C)c1
b. OC1OC[C@@H](O)[C@H](O)[C@H]1O
c. COC(=O)C1C2C=CC(C3CC23)C1C(=O)OCC(=O)c1ccccc1
Answer: c. COC(=O)C1C2C=CC(C3CC23)C1C(=O)OCC(=O)c1ccccc1
