Task: Answer the MCQ question.
Question: Which drug exhibits a 1.939\% 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) CC(/C=C/c1ccccc1)=N\Nc1nc(-c2ccccc2)cs1
(b) COC(=O)/C(N=Nc1c(C)n(C)n(-c2ccccc2)c1=O)=C(\C)O
Answer: a. CC(/C=C/c1ccccc1)=N\Nc1nc(-c2ccccc2)cs1
