In the question below is given a statement followed by two options numbered 1 and 2. Based on this choose the correct option. Statement: Pectin is a type of structural fibre made up of few hundred to thousand galacturonic monomer units found in fruits, such as apples, oranges, lemons, etc. Option 1 - Citrus fruit contains 5% – 7.5% pectin which is largely present in the juice of the fruit. Option 2 - During the ripening process, pectin changes to a water-insoluble material from a water-soluble substance.

Correct option is D

Pectin is a water-soluble dietary fibre primarily found in the cell walls and middle lamella of plant tissues, not in fruit juice.
The concentration of pectin in citrus fruits is typically around 0.5% to 3.5%, not 5% to 7.5% as claimed in option 1.
Moreover, pectin is mostly present in the peel and pith (albedo) of citrus fruits, not in the juice.
Therefore, Option 1 is factually incorrect.
During the ripening process, the opposite of Option 2 occurs.
Initially, pectin is in a water-insoluble form in unripe fruits.
As the fruit ripens, enzymatic activity breaks down insoluble pectin into water-soluble forms, making the fruit softer.
Hence, Option 2 is also incorrect.
Option 2 incorrectly reverses the actual ripening-related transformation of pectin.
Both Option 1 and Option 2 provide factually incorrect statements.
Hence, the correct answer is that both 1 and 2 are incorrect.
