D.10%10\% solution of Na2CO3.N{{a}_{2}}C{{O}_{3}}.

Explanation

Solution

We know that the lye is a metal hydroxide typically obtained by leaching wood ashes, or a powerful alkali that is highly soluble in caustic basic solutions formed by water. 'Lye' refers most generally to sodium hydroxide.

Complete answer:
Lye is an alkaline solution that is produced by the reaction of wood ashes and water. The process is called leaching. Lye is commonly used for making soaps and washing. It can also be considered as a strongly alkaline solution like potassium hydroxide or sodium hydroxide. Lye is used in the making of soap in the form of both sodium hydroxide and potassium hydroxide. Potassium hydroxide soaps are smoother than sodium hydroxide soaps and are more readily dissolved in water.
Sodium hydroxide and potassium hydroxide, either in the quantities necessary or in the properties created in soap making, are not interchangeable. Soap making "hot operation" also uses lye as the main ingredient. Lye is added to the bath, cooled, and then added to the oils and butter for a few minutes. Over some time (one-two hours), usually in a slow cooker, the mixture is then cooked and then put in a mold. As it does not take several weeks to complete, this technique is much faster than the cold process.
Therefore, correct answer is option B i.e. 10%10\% solution of NaOH.NaOH.

Additional Information: Sodium hydroxide lye (or caustic soda lye) and potassium hydroxide lye are widely used in soap production. In general, potassium hydroxide soaps are more readily soluble in water and are softer than the caustic soda lye. These caustic lye soaps are not found to be interchangeable; they have separate sets of properties and are widely used for different purposes.

Note:
Remember that since Lye solutions are alkaline in nature, they are coarse on human skins. Therefore, proper care must be taken while handling lye solutions. Lye can cause skin blisters when coming in contact. It can also lead to tissue decomposition if a high concentration of lye solution is in contact with the body.
