Given below are two statements. One is labelled as Assertion A and the other is labelled as Reason R.

Assertion A: Amylose is insoluble in water.

Reason R: Amylose is a long linear molecule with more than 200 glucose units.

In the light of the above statements, choose the correct answer from the options given below.

Multiple Choice Options

  • A Both A\mathbf{A} and R\mathbf{R} are correct and R\mathbf{R} is the correct explanation of A\mathbf{A} .
  • B Both A\mathbf{A} and R\mathbf{R} are correct but R\mathbf{R} is NOT the correct explanation of A\mathbf{A} .
  • C A\mathbf{A} is correct but R\mathbf{R} is not correct
  • D A\mathbf{A} is not correct but R\mathbf{R} is correct.

Step-by-Step Verified Solution

Let's analyze the given statements:

Assertion A: "Amylose is insoluble in water." This statement is incorrect. Amylose is actually soluble in water, although its solubility is lower compared to other carbohydrates like amylopectin.

Reason R: "Amylose is a long linear molecule with more than 200 glucose units." This statement is correct, as amylose is indeed a linear polysaccharide made up of glucose units.

Given this information, the correct option is:

Option D: A\mathbf{A} is not correct but R\mathbf{R} is correct.
