Task: Answer the multiple choice question.
Question: Which compound exhibits a -1.457\% 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] COc1ccc(NC2CCCN(C(=O)C3=NN(C)C(=O)CC3)C2)cc1OC
[b] O=C1Nc2c(c(=O)[nH]c(=O)n2-c2ccccc2)C(C(F)(F)F)(C(F)(F)F)N1
[c] Cc1cc(N2CCCC2)ccc1NC(=O)COc1cccc(C(F)(F)F)c1
[d] S=C(NC1CCCC1)NN1CCOCC1
Answer: b. O=C1Nc2c(c(=O)[nH]c(=O)n2-c2ccccc2)C(C(F)(F)F)(C(F)(F)F)N1
