Problem statement: Answer the multiple choice question.
Query: Which compound has a 2.711\% 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. COc1ccc(CN(C(=O)Cc2c[nH]c3ccccc23)C(C(=O)NC2CCCCC2)c2ccc(C)o2)cc1
b. O=C1S/C(=C\c2ccc(N3CCOCC3)o2)C(=O)N1c1ccccc1
c. C=CCSC1=N/C(=C\c2cc(OCC)c(OC(C)=O)c([N+](=O)[O-])c2)C(=O)S1
Answer: c. C=CCSC1=N/C(=C\c2cc(OCC)c(OC(C)=O)c([N+](=O)[O-])c2)C(=O)S1
