Task: Answer the MCQ question.
Query: Which drug exhibits a 1.878\% human ether-à-go-go related gene (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) COc1ccc(CN(C(=O)CSc2nnc(-c3ccccc3C)o2)c2ccc(F)cc2)cc1
b) COc1ccccc1C1C(C(N)=O)=C(C)Nc2nc(-c3ccc(Cl)cc3)nn21
Answer: b. COc1ccccc1C1C(C(N)=O)=C(C)Nc2nc(-c3ccc(Cl)cc3)nn21
