The Solubility of NaCH₃CO₂ in Water Is ~1

The solubility of NaCH₃CO₂ in water is ~1.23 g/mL. What would be the best method for preparing a supersaturated NaCH₃CO₂ solution?

A) add 130 g of NaCH₃CO₂ to 100 mL of H₂O at 80 °C while stirring until all the solid dissolves, then let the solution cool to room temperature
B) add 123 g of NaCH₃CO₂ to 200 mL of H₂O at 80 °C while stirring until all the solid dissolves, then let the solution cool to room temperature
C) add 130 g of NaCH₃CO₂ to 100 mL of H₂O at room temperature while stirring until all the solid dissolves
