Task: Answer the multiple-choice question.
Query: Which compound has a 3.780\% 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) C=CC[C@@H]1C=C[C@H](O/N=C/[C@@H](NS(=O)(=O)c2ccc(C)cc2)[C@H](C)/C=C/CC(=O)OC)[C@@H](CO)O1
(b) COc1ccccc1C=NC(CO)C(O)c1ccc([N+](=O)[O-])cc1
Answer: b. COc1ccccc1C=NC(CO)C(O)c1ccc([N+](=O)[O-])cc1
