Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 10.050\% 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 additional words.
Options:
a. N#Cc1cccc(Cn2nnc(-c3ccccc3)n2)c1
b. CC(=O)NCCC(=O)Nc1ccc(C)c(F)c1
c. O=c1c(Oc2ccccc2Br)c(C(F)(F)F)oc2c(CN3CCCC3)c(O)ccc12
d. O=[N+]([O-])c1ccccc1Cl
Answer: d. O=[N+]([O-])c1ccccc1Cl
