Task: Answer the multiple choice question.
Question: Which compound has a 28.721\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a.) O=C1N/C(=N\S(=O)(=O)Cc2ccccc2)S/C1=C/c1cccc([N+](=O)[O-])c1
b.) COc1ccc(CN(C)C(=O)c2[nH]c(C)c(C(C)=O)c2C)c(OC)c1OC
c.) CCC(C)n1c(O)c(C=NCCN2CCOCC2)c(=O)[nH]c1=S
Answer: a. O=C1N/C(=N\S(=O)(=O)Cc2ccccc2)S/C1=C/c1cccc([N+](=O)[O-])c1
