Task: Answer the multiple choice question.
Question: Which drug exhibits a -67.654% 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] O=C(NCCc1c[nH]c2ccccc12)/C(=C/c1cccnc1)NC(=O)c1ccco1
[b] CCC(=O)N1CCN(c2ccc(NC(=O)c3cc4ccccc4o3)cc2Cl)CC1
Answer: b. CCC(=O)N1CCN(c2ccc(NC(=O)c3cc4ccccc4o3)cc2Cl)CC1
