The hydrolysis of esters in base is called saponification .
So, option C is correct one.
The saponification is the process that involves conversion of fats , oils , lipids into soap and water in the presence of alkaline medium. Saponification is the process of making soap.
During the saponification process, the mixture has an acidity, which tells that it's not safe for usage. After the saponification process is complete, the pH should be a base.The process of formation of carboxylic salt and water by hydrolysis of ester in base is called saponification.

Answers:
0.606 g H₂
Step-by-step explanation:
We know we will need a balanced equation with masses and molar masses, so let’s gather all the information in one place.
M_r: 39.10 2.016
2K + 2H₂O ⟶ 2KOH + H₂
m/g: 23.5
(a) Calculate the <em>moles of K
</em>
n = 23.5 g K × 1 mol K /39.10 g K
n = 0.6010 mol K
(b) Calculate the moles of H₂
The molar ratio is (1 mol H₂/2 mol K)
n = 0.6010 mol K × (1 mol H₂/2 mol K)
n = 0.3005 mol H₂
(c) Calculate the <em>mass of H₂</em>
m = 0.3005 mol H₂ × (2.016 g H₂/1 mol H₂)
m = 0.606 g H₂
