Task: Answer the multiple choice question.
Question: Which compound has a -3.692\% 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 other words.
Options:
a) Cc1ccc(Nc2c([N+](=O)[O-])cc(C(=O)N3CC(=O)Nc4ccccc43)cc2[N+](=O)[O-])c(C)c1
b) CCN(CCO)c1ccc(-n2c(N)c(C(=O)OC)c3nc4ccccc4nc32)cc1
c) O=C(Cc1csc(N2CCOCC2)n1)N/N=C/c1ccc(Cl)cc1Cl
d) Cc1ccc(NC(=O)C2CCN(S(=O)(=O)c3cccc4nonc34)CC2)nc1
Answer: b. CCN(CCO)c1ccc(-n2c(N)c(C(=O)OC)c3nc4ccccc4nc32)cc1
