Demineralized water can be obtained by using:

1. Cation Exchange Resin: This process involves the exchange of cations in the water with hydrogen ions. This is effective in removing minerals such as calcium and magnesium which are positively charged.

2. Anion Exchange Resin: This process involves the exchange of anions in the water with hydroxyl ions. This is effective in removing minerals such as chloride and sulfate which are negatively charged.

3. Reverse Osmosis: This process involves forcing water through a semi-permeable membrane under pressure. The membrane allows water molecules to pass through but blocks the passage of larger ions or molecules, including most minerals.

4. Osmosis: This is not typically used to demineralize water, as it is a natural process where water moves from an area of low solute concentration to an area of high solute concentration, usually through a semi-permeable membrane. This process would not remove minerals from water.

So, the correct answers are Cation Exchange Resin, Anion Exchange Resin, and Reverse Osmosis.
