    c. By brine curing

    Explanation:

    Tanning refers to the process of treating the hides and skins of animals to produce leather. The different processes involved in the tanning of leather include:

    Curing: this is the process of applying salt to the animal hide to prevent decay from bacterial growth. It also serves to reduce the moisture content of the animal hide.

    Soaking : this involves soaking the hides in clean water to remove the salt left over from curing and increase the moisture content for further treatment of the hide.

    Liming: Liming is done by applying lime to remove hair, fat and grease and in order for the hide to swell up.

    Scudding: This is the process of further removal of usually done first by a machine, and then manually using a dull knife.

    Deliming: This is done using an acid to reduce the pH of the collagen found in the hide being tanned.
