Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 1.466\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a) O=C(c1ccco1)N1CCN(C2c3ccccc3-c3ccccc32)CC1
b) Cc1nc2ccc3ccccc3c2o1.O=[N+]([O-])c1cc([N+](=O)[O-])c(O)c([N+](=O)[O-])c1
c) Cn1c(=O)c([N+](=O)[O-])c(NCc2ccccc2Cl)c2ccccc21
d) Nc1c(C(=O)O)cnc2nc(N3CCOCC3)nn12
Answer: c. Cn1c(=O)c([N+](=O)[O-])c(NCc2ccccc2Cl)c2ccccc21
