Task: Answer the multiple choice question.
Query: Which compound has a 13.840\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a COc1ccc(-c2noc(CNS(=O)(=O)c3ccc(NC(C)=O)cc3)n2)cc1OC
b O=C(Nc1cccc(O)c1)c1ccc(NC(=O)c2cccs2)cc1
c CC1(C)Cc2c(c(=S)nc(-c3ccccc3)n2CCOCCO)CO1
d O=C(O)CC/C(=N/NC(=O)c1cn(-c2ccccc2)nc1-c1ccccc1)C(=O)O
Answer: b. O=C(Nc1cccc(O)c1)c1ccc(NC(=O)c2cccs2)cc1
