Answer:

The addition of sugar and salt to the food material result in the increase in the osmotic pressure, which help to destroy the bacteria and help in the preservation of food.

Explanation:

addition of salt or sugar help to preserve food because

by adding salt to the food material it absorbs the water and high concentration of salt inhibit the growth of microbe and if the water is not present in food bacteria will not able to reproduce by this way addition of salt help in the preservation of food.
by adding sugar to the food material it reduces the water content which prevent the food from microbial spoilage.if the sugar concentration is high ,the bacteria to lose water and if enough water is not present bacteria will not able to grow

thus by this way addition of salt or sugar help preserve food.

The correct answer would be D) tissue.

In biology, the level of organisation from simplest to complex level can be summarized as:

Organelles → cells → tissues → organs → organ systems → organisms → populations →communities → ecosystem → biosphere.

It is clear that tissue is organization level that exists between cells and organs.

When similar cells are assembled together to perform specific function, the assembly or this organization is said to be the tissue.

There can be different types of tissues such as muscle tissue, nerve tissue et cetera.

Similarly, tissues arrange themselves to carry out specific function in the form of organ.
