Task: Answer the multiple choice question.
Question: Which drug exhibits a 18.984\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a CCN(CC)c1ccc(/C=N/O)cc1
b Cc1cc(C(=O)N/N=C/C(Cl)=C/c2ccccc2)c(C)o1
Answer: a. CCN(CC)c1ccc(/C=N/O)cc1
