A
Fish & Meats
B
Fruits & Veggies
C

D
Herbs & Minerals
Explanation: 

Detailed explanation-1: -Salt is effective as a preservative because it reduces the water activity of foods. The water activity of a food is the amount of unbound water available for microbial growth and chemical reactions.

Detailed explanation-2: -It is one of the oldest methods of preserving food, and two historically significant salt-cured foods are salted fish (usually dried and salted cod or salted herring) and salt-cured meat (such as bacon). Vegetables such as runner beans and cabbage are also often preserved in this manner.

Detailed explanation-3: -Salted fish, such as kippered herring or dried and salted cod, is fish cured with dry salt and thus preserved for later eating. Drying or salting, either with dry salt or with brine, was the only widely available method of preserving fish until the 19th century.

Detailed explanation-4: -The salt has a preserving effect as it extracts water from the fish muscle and transports salt into it. The salt lowers the water activity inside the muscle, making the remaining water less accessible for microorganisms, which inactivates or inhibits microbial growth.
