Task: Answer the multiple-choice question.
Question: Which drug has a 10.126\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: O=C(Nc1ccc(N2CCOCC2)cc1)c1ccc(Br)o1
b: Cc1cc(C(=O)N2CCCC(C(=O)c3ccc4ccccc4c3)C2)n(C)n1
Answer: a. O=C(Nc1ccc(N2CCOCC2)cc1)c1ccc(Br)o1
