Hint: We know that when sodium peroxide dissolves in hot water, then it forms sodium hydroxide and oxygen. When sodium peroxide dissolves in cold water, then it forms sodium hydroxide and hydrogen peroxide.

Complete answer:
Try to recall that sodium reacts with the oxygen in the air to form sodium oxide and sodium oxide reacts with moisture and carbon dioxide to release oxygen gas. We know that sodium is found in nature in combination with other elements. It’s the seventh element for their abundance in the earth crust and is an essential component of plants and animals. It is a metal with the silvery appearance and is very soft, highly reactive and when it is exposed to air is easily oxidized. When sodium is exposed to air, it is oxidised to sodium peroxide which is yellow solid by atmospheric oxygen.
Sodium peroxide is a white solid which is used as a bleaching agent, disinfectant and in the production of other chemicals. Also, you should remember that sodium does not form superoxide on reaction with oxygen because superoxide anion is large, so sodium which is a small superoxide on reaction with oxygen because superoxide anion is large, so sodium which is a small cation could not stabilize it.
When hydrogen peroxide reacts with \[NaOH\], it forms sodium peroxide.
The reaction is as follows: \[2NaOH+{{H}_{2}}{{O}_{2}}\to N{{a}_{2}}{{O}_{2}}+2{{H}_{2}}O\] ; can show its ability to neutralize bases such as \[NaOH\]to form corresponding peroxides.
Therefore, the correct answer is option B.

Note:
Remember that the reaction of sodium peroxide with water follows two conditions i.e. with hot water and with cold water. In both the reactions products are different so you must check whether the question is asking for hot water or for cold water.
