The major active component in the water extract of the ash obtained by burning banana plant, used as a substitute for soda by villagers in some parts of India, is sodium carbonate. Sodium carbonate is also known as soda ash or washing soda.

Let`s go through the other options to understand why they are not the major active component in this case:

Option 2: Potassium carbonate - Although potassium is present in banana plants, it is not the major active component in the extract.

Option 3: Calcium oxide - Calcium oxide, also known as lime or quicklime, is not the major active component in the extract.

Option 4: Magnesium oxide - Magnesium oxide, commonly known as magnesia, is not the major active component in the extract.

Therefore, the correct answer is option 1, Sodium Carbonate.
