Task: Answer the multiple choice question.
Question: Which drug exhibits a -10.680\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: CN(CC(=O)N1CCCCCC1)S(=O)(=O)c1ccc(Br)s1
b: CCOC(=O)C1CCN(c2ncnc3c2cnn3-c2ccccc2)CC1
c: CC(NC(=O)C1(S(=O)(=O)c2ccc(Cl)cc2)CC1)c1ccccc1
d: CCOc1cccc2sc(N(CCCN(C)C)C(=O)c3ccc(S(=O)(=O)N(C)CC4CCCO4)cc3)nc12.Cl
Answer: b. CCOC(=O)C1CCN(c2ncnc3c2cnn3-c2ccccc2)CC1
