What's the best method of storing yeast for 4 to 6 months in the refrigerator? Homebrewing

I've done a bit of research into different options of yeast storage and so far the least time consuming and most accessible methods seem to be:

• Making a slant from a yeast sample taken directly from a freshly opened liquid yeast packet.

• Taking a small quantity (about 5 mL) from a freshly open liquid yeast packet and storing it in a tightly capped test tube under distilled and deoxygenated water.

• Taking a small quantity (about 5 mL) from a freshly open liquid yeast packet and storing it in a tightly capped test tube under 1.030 SG wort + yeast nutrient.

• Making a starter with the liquid yeast packet and saving 10 mL of the yeast slurry in a tightly capped test tube.

All of the above methods will be done under sterile conditions and stored in the refrigerator.

Which one will work best for storing yeast for 4 months or so?
