Answer 1

The Correct Option is C

Step 1: Understanding food preservation methods.
Food preservation methods include removing heat, irradiating, and adding heat. However, adding water is not a common method of food preservation because water can facilitate the growth of microorganisms.
Step 2: Analyzing the options.
(A) Removal of heat: This is a common method (e.g., freezing) used to preserve food.
(B) Irradiation: This method involves exposing food to radiation to kill bacteria and extend shelf life.
(C) Addition of water: Correct — Adding water is generally not a preservation method, as it can promote spoilage.
(D) Addition of heat: This is another common method (e.g., pasteurization) for preserving food.
Step 3: Conclusion.
The correct answer is (C) Addition of water.
