Task: Answer the multiple choice question.
Query: Which drug has a 7.229\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: O=C(COC(=O)/C=C/c1cccc([N+](=O)[O-])c1)NCCCN1CCCC1=O
b: COc1ccc(-c2nc(CC(=O)O)cs2)cc1OC
c: Cc1ccc(CN(CC(=O)NCCc2ccccc2)C(=O)CCCC(=O)Nc2cc(C)on2)cc1
Answer: a. O=C(COC(=O)/C=C/c1cccc([N+](=O)[O-])c1)NCCCN1CCCC1=O
