Task: Answer the multiple-choice question.
Query: Which drug exhibits a 6.207% 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 COc1cc(C(C[N+](=O)[O-])c2c(C)cc3ccccn23)ccc1O
b O=C(CN1CCN(c2ccccn2)CC1)Nc1cccc(F)c1
c Cc1ccn(C)c(=N)c1
Answer: a. COc1cc(C(C[N+](=O)[O-])c2c(C)cc3ccccn23)ccc1O
