Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 4.221\% 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) O=[N+]([O-])c1cnccc1Nc1cccc(F)c1
b) Cc1ccc(C)n1-c1sc2c(c1C(=O)O)CCCC2
c) O=C(c1ccccc1)N1CCN(c2nc3ccc([N+](=O)[O-])cc3s2)CC1
Answer: a. O=[N+]([O-])c1cnccc1Nc1cccc(F)c1
