Task: Answer the multiple choice question.
Question: Which compound has a 7.500\% 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 other words.
Options:
a) CC1(C)CC(=O)C2=C(C1)OC(N)=C(C#N)C2C1CC=CCC1
b) O=C(Nc1cccc(Cl)c1Cl)c1ccncc1
c) CNCC(=O)Nc1ccc(Cl)c(C(F)(F)F)c1
d) COc1ccc(C(=O)C2CCCN(Cc3sc(N4CCCC4)nc3Cl)C2)c(OC)c1
Answer: c. CNCC(=O)Nc1ccc(Cl)c(C(F)(F)F)c1
