Task: Answer the multiple choice question.
Question: Which drug has a -1.990% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a. CC(=O)Nc1cccc(C(=O)OC2CCOC2=O)c1
b. CCOc1ccc(CCNC(=O)CN2CCN(Cc3ccc(F)cc3)C2=O)cc1OCC
c. O=C1CCC(CCC(=O)N2CCCC(C(=O)c3ccc(Cl)cc3)C2)=NN1
d. NC(=O)CC(NC(=O)Cc1ccc(Br)cc1)c1ccc(NC2CC3CCC2C3)c([N+](=O)[O-])c1
Answer: a. CC(=O)Nc1cccc(C(=O)OC2CCOC2=O)c1
