Task: Answer the multiple choice question.
Question: Which compound exhibits a -19.586\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a. O=c1[nH]c(CSc2nc3ccccc3[nH]2)nc2c1cnn2-c1ccccc1
b. COc1ccc([N+](=O)[O-])cc1C(=O)NC1CCN(Cc2ccccc2)CC1.Cl.O
c. O=C(CSc1ccc(-c2cccnc2)nn1)Nc1ccc(F)cc1F
d. O=C(O)CSc1nnc(-c2ccccc2Br)n1-c1cccc(C(F)(F)F)c1
Answer: b. COc1ccc([N+](=O)[O-])cc1C(=O)NC1CCN(Cc2ccccc2)CC1.Cl.O
