Task: Answer the multiple-choice question.
Question: Which drug has a 11.673\% 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(C2C([N+](=O)[O-])=C(C)N(C)C(=O)N2C)cc1OC
[b] CCOC(=O)c1cc(OC(=O)c2cccs2)n(-c2ccccc2)n1
[c] CCOC(=O)C1=C(COC(=O)CCNS(=O)(=O)c2ccc(C)c(C)c2)NC(=O)NC1C
Answer: a. COc1ccc(C2C([N+](=O)[O-])=C(C)N(C)C(=O)N2C)cc1OC
