Problem statement: Answer the MCQ question.
Question: Which drug exhibits a -1.920\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] CCC1=NN(C(=O)Cc2ccc([N+](=O)[O-])cc2)C(O)(C(F)(F)F)C1
[b] CC(C)=CCN1CCN(Cc2cccnc2)CC1CCO
[c] CCC(=O)c1ccc(OCC(=O)OCC(=O)N2CCCc3ccccc32)cc1
[d] COc1ccc(C2C(C(=O)OC3CCCCC3)=C(C)Nc3nnnn32)c(OC)c1OC
Answer: d. COc1ccc(C2C(C(=O)OC3CCCCC3)=C(C)Nc3nnnn32)c(OC)c1OC
