Task: Answer the multiple-choice question.
Query: Which compound has a 2.385\% 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) O=C(NCCc1ccc(Cl)cc1)/C(=C/c1cccnc1)NC(=O)c1ccccc1
(b) C[C@@H](O)[C@@H]1NC(=O)c2cc([N+](=O)[O-])cc(I)c2NCC[C@@H](C(N)=O)NC(=O)CNC1=O
Answer: b. C[C@@H](O)[C@@H]1NC(=O)c2cc([N+](=O)[O-])cc(I)c2NCC[C@@H](C(N)=O)NC(=O)CNC1=O
