Task: Answer the MCQ question.
Question: Which compound exhibits a 2.470\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a) O=C(CN1CC(c2ccccc2)CC1=O)Nc1ccc2c(c1)OCO2
b) O=C(O)c1cc(-c2ccc(/C=N/Nc3ccc(Cl)cc3)o2)ccc1Cl
c) O=C(Nc1cnccn1)c1cccc(C(F)(F)F)c1
Answer: c. O=C(Nc1cnccn1)c1cccc(C(F)(F)F)c1
