Task: Answer the multiple choice question.
Query: Which compound has a -3.983\% 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. CC(=O)Nc1cccc(NC(=O)CSc2nnnn2C(C)C)c1
b. C=CCSC1=NNC(c2ccc(C(C)(C)C)cc2)=NN1
c. N#Cc1c(N)nc2c(c1-c1cccs1)CCCC2
d. O=C(CN1C(=O)c2cccc3cccc(c23)C1=O)N1CCN(c2ccccn2)CC1
Answer: d. O=C(CN1C(=O)c2cccc3cccc(c23)C1=O)N1CCN(c2ccccn2)CC1
