Problem statement: Answer the multiple choice question.
Query: Which drug has a -23.498\% 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(c1ccccn1)C1CCCN(Cc2cn[nH]c2-c2cc3ccccc3o2)C1
[b] Cc1ccccc1C(=O)Nc1ccc(O)cc1C(=O)O
Answer: a. O=C(c1ccccn1)C1CCCN(Cc2cn[nH]c2-c2cc3ccccc3o2)C1
