"F1F1F1S1F1F1F10-arrestin" prevents GPCR from reassociating with the GF1F1F1S1_F1F1F10F1F1F1S1_F1F1F10F1F1F1S1_F1F1F10complex by binding to the activated G protein-coupled receptor, preventing it from interacting with the G protein and instead promoting its internalization and desensitization. The other options listed have different functions and do not prevent reassociation of GPCR with the complex.
