Task: Answer the multiple-choice question.
Query: Which drug has a 9.941\% 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] CCN1C(=O)C(=O)N(Cc2ccc(OC)c(F)c2)C1=O
[b] CC(=O)NC(Cc1ccc(F)c(F)c1)C(=O)NC1CCN(c2c(Cc3ccccc3)c(C)nc3ncnn23)CC1
[c] Cc1cccc(OCC(=O)O/N=C(\N)c2ccncc2)c1
Answer: a. CCN1C(=O)C(=O)N(Cc2ccc(OC)c(F)c2)C1=O
