Task: Answer the multiple choice question.
Question: Which drug exhibits a 18.026\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] CC(C)(C)C(=O)OCCn1c(=O)c2cc3c(=O)n(CCOC(=O)C(C)(C)C)c(=O)c3cc2c1=O
[b] COc1cc(C2C(C(=O)c3ccc(C)o3)=C(O)C(=O)N2c2cc(C)on2)ccc1O
[c] CCOc1ccc(NC(=S)Nc2cc(OC)c(Cl)cc2OC)cc1
Answer: a. CC(C)(C)C(=O)OCCn1c(=O)c2cc3c(=O)n(CCOC(=O)C(C)(C)C)c(=O)c3cc2c1=O
