Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 18.591\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) O=C(N/N=C/c1cccc(O)c1)c1ccccc1O
(b) O=C(Nc1ccccc1-c1ccccc1)C(c1ccccc1)c1ccccc1
(c) O=C(COC(=O)Cc1ccccc1[N+](=O)[O-])NC1CCCC1
Answer: b. O=C(Nc1ccccc1-c1ccccc1)C(c1ccccc1)c1ccccc1
