Task: Answer the multiple choice question.
Question: Which drug has a 8.264\% 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] Cc1cc(N)n2nc(-c3ccccc3)c(-c3ccccc3)c2n1
[b] C=CCn1c(NCCOC)nc2c1c(=O)n(C)c(=O)n2C
[c] COc1ccccc1NC(=O)c1nnn(CC(=O)Nc2ccccc2)c1N
Answer: b. C=CCn1c(NCCOC)nc2c1c(=O)n(C)c(=O)n2C
