Task: Answer the multiple-choice question.
Question: Which drug exhibits a -22.735\% 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 COc1ccc2nc(N3CCCC(O)C3)c(C#N)cc2c1
b Cc1cccc(OCC(=O)Nc2nc3ccc([N+](=O)[O-])cc3s2)c1C
c O=C(c1cccc(C(=O)N2CCN(c3ccc(F)cc3)CC2)c1)N1CCN(c2ccc(F)cc2)CC1
d Cc1nn(-c2ccc(Cl)cc2)c(=O)c2ccccc12
Answer: c. O=C(c1cccc(C(=O)N2CCN(c3ccc(F)cc3)CC2)c1)N1CCN(c2ccc(F)cc2)CC1
