Task: Answer the multiple choice question.
Query: Which drug exhibits a -52.087\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
[a] COC(=O)c1cc(NC(=O)Cc2ccc(OC)cc2)cc(C(=O)OC)c1
[b] CCCCCCCNC(=O)C1(CC2CC(c3ccc(Cl)cc3)=NO2)CCN(C(=O)CCCCCBr)CC1
Answer: b. CCCCCCCNC(=O)C1(CC2CC(c3ccc(Cl)cc3)=NO2)CCN(C(=O)CCCCCBr)CC1
