Task: Answer the multiple-choice question.
Query: Which drug exhibits a -44.997% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] Cc1cc(OCC(=O)NC2CC(C)(C)NC(C)(C)C2)c(C)cc1Br
[b] O=C(C1=C[C@@H](c2ccccc2)C[C@@H](OCc2ccc(CO)cc2)O1)N1CCOCC1
[c] O=c1c(Br)c(N2CCCC2)cnn1-c1ccccc1
Answer: b. O=C(C1=C[C@@H](c2ccccc2)C[C@@H](OCc2ccc(CO)cc2)O1)N1CCOCC1
