Task: Answer the multiple choice question.
Question: Which compound has a 8.218\% 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=c1c2c(c(-c3ccccc3)nn1Cc1ccccc1)CCCC2
b) Cc1ccc(NC(=O)CS(=O)CC(=O)Nc2ccc(N3CCOCC3)cc2)cc1Cl
c) CCCc1cc(=O)c2c(O)ccc(OC)c2o1
Answer: a. O=c1c2c(c(-c3ccccc3)nn1Cc1ccccc1)CCCC2
