Task: Answer the multiple choice question.
Question: Which drug has a 1.702\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
(a) COC(=O)/C=C/C(=O)Nc1ccc(O)c(Cl)c1
(b) CCOc1ccc(Br)cc1C(=O)N/N=C/c1c[nH]c2ccccc12
Answer: a. COC(=O)/C=C/C(=O)Nc1ccc(O)c(Cl)c1
