Task: Answer the multiple choice question.
Question: Which drug has a 9.930\% 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, b, or c without using any other words.
Options:
[a] COc1ccc(Br)cc1CN(C)C(=O)c1ccncc1
[b] CCCc1cc(=O)[nH]c(SCC(=O)c2ccc3c(c2)NC(=O)CO3)n1
[c] COc1ccc(CC2CCOC2=O)cc1
Answer: a. COc1ccc(Br)cc1CN(C)C(=O)c1ccncc1
