Task: Answer the multiple choice question.
Query: Which drug exhibits a 4.497\% 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] COc1ccc(Cc2nc3ccccc3c(=O)n2N)cc1OC
[b] COc1ccc(/C=C/C(=O)c2ccc[nH]2)c(OC)c1OC
[c] Cc1ccccc1/C=N/NC(=O)Cn1cnc([N+](=O)[O-])n1
Answer: b. COc1ccc(/C=C/C(=O)c2ccc[nH]2)c(OC)c1OC
