Task: Answer the MCQ question.
Question: Which compound exhibits a 6.452\% 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(Nc1ccccc1F)Nc1ccccc1OC(F)F
b.) C/C(N)=C(/C#N)C(=O)CSc1nc2ccccc2c(=O)n1CCCOC(C)C
c.) COCCNC(=O)C1Nc2ccc(C(F)(F)F)cc2C2C=CCC12
Answer: a. O=C(Nc1ccccc1F)Nc1ccccc1OC(F)F
