Task: Answer the multiple choice question.
Question: Which compound exhibits a 19.424\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a. O=C(Nc1ccc2c(c1)OCO2)C1CC(c2ccc(F)cc2)=NO1
b. O=C(C1CCCCC1)N1CCCC(c2nc3c(nnn3Cc3ccccc3)c(=O)[nH]2)C1
c. COc1ccc(/C=N/N=C(\N)c2nonc2N)cc1OC
Answer: c. COc1ccc(/C=N/N=C(\N)c2nonc2N)cc1OC
