Problem statement: Answer the multiple choice question.
Query: Which drug has a 7.843\% 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: CCOC(=O)N/N=C/c1cc(C)n(-c2ccccc2)c1C
b: COc1ccc(C)cc1Nc1nc(N)c2cc(OC)c(OC)cc2n1
Answer: a. CCOC(=O)N/N=C/c1cc(C)n(-c2ccccc2)c1C
