Task: Answer the multiple choice question.
Question: Which drug has a 9.175\% 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 additional words.
Options:
a. CC1(C)COC(c2cccn2Cc2ccccc2Cl)=N1
b. O=[N+]([O-])c1cccc(Cl)c1N1CCOCC1
c. Cc1ccc(CN2CCN(Cc3cccn3-c3ccccn3)CC2CCO)o1
d. O=C(NNC(=O)C1CC=CCC1)c1ccccc1Br
Answer: b. O=[N+]([O-])c1cccc(Cl)c1N1CCOCC1
