Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -5.120\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a.) Cc1ccc(CN2C(=O)C(C)(C)Oc3ccc(C(=O)N4CCCCC4)cc32)cc1
b.) O=C(Cn1cnc2scc(-c3ccc(Br)cc3)c2c1=O)N1CCOCC1
Answer: b. O=C(Cn1cnc2scc(-c3ccc(Br)cc3)c2c1=O)N1CCOCC1
