Which fruit is rich in pectin?

Correct option is C

Apple is rich in pectin, a soluble fiber used in food processing for making jellies and jams due to its gelling properties.

pectin content is highest in apples, especially in unripe apples, which is why apple pomace is widely used in the food industry to extract commercial pectin.

Cashew apple contains some pectin, but its pectin content is significantly lower than that of apples, and it is not considered a commercial pectin source.
