Task: Answer the MCQ question.
Question: Which drug has a 21.404% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a N=C1C(c2ccccc2)=C(O)CN1c1cccc(O)c1
b CN(C(=O)Cc1ccc(Cl)c(Cl)c1)[C@H]1CCCC[C@H]1N1CCCC1.O=C(O)C(O)C(O)C(=O)O
Answer: a. N=C1C(c2ccccc2)=C(O)CN1c1cccc(O)c1
