Task: Answer the multiple-choice question.
Query: Which drug exhibits a 0.484\% 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: CCOc1ccc(CCNC(=O)c2cnccn2)cc1OCC
b: O=C(CCc1ccc(Oc2cc([N+](=O)[O-])cc([N+](=O)[O-])c2)cc1)NC1CCCC1
Answer: b. O=C(CCc1ccc(Oc2cc([N+](=O)[O-])cc([N+](=O)[O-])c2)cc1)NC1CCCC1
