Task: Answer the multiple choice question.
Query: Which drug exhibits a -6.003% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] COC(=O)[C@@H](Cc1c[nH]c2ccccc12)NC(=O)CCC(=O)c1ccc(Br)cc1
[b] CCOc1ccc(-c2n[nH]c(C(=O)NN)c2C)cc1
Answer: a. COC(=O)[C@@H](Cc1c[nH]c2ccccc12)NC(=O)CCC(=O)c1ccc(Br)cc1
