Task: Answer the MCQ question.
Query: Which drug exhibits a 6.890\% 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: CCc1cc([N+](=O)[O-])cc(CC)c1N
b: CCc1sc(N2C(=O)C3C4CCC(C4=C(C)C)C3C2=O)nc1-c1ccccc1
c: Cc1ccc(C)c(NC(=O)C2COc3ccccc3O2)c1
d: CC1=C(C(=O)OCc2ccccc2)C(c2ccccc2OS(=O)(=O)c2ccc([N+](=O)[O-])cc2)NC(=O)N1CCCC(=O)O
Answer: d. CC1=C(C(=O)OCc2ccccc2)C(c2ccccc2OS(=O)(=O)c2ccc([N+](=O)[O-])cc2)NC(=O)N1CCCC(=O)O
