Task: Answer the multiple choice question.
Question: Which drug has a -23.857% 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. O=S(=O)(NCCC1=CCCCC1)c1ccc(F)cc1
b. CCN1C(=NCC(C)C)N[C@@H](c2cccc(C(F)(F)F)c2)C(C(=O)OC)=C1C
c. O=C(/C=C/Nc1ccc(Br)cn1)c1cccc(OC(F)F)c1
Answer: b. CCN1C(=NCC(C)C)N[C@@H](c2cccc(C(F)(F)F)c2)C(C(=O)OC)=C1C
