The correct Answer is:
To determine the correct answer based on the given statements about biomolecules, we will analyze each statement step by step. ### Step 1: Analyze Statement (i) **Statement (i)**: Cellulose is a homopolymer of glucose. - **Explanation**: Cellulose is indeed a homopolymer, meaning it is made up of only one type of monomer. In this case, the monomer is glucose. Cellulose consists of long chains of glucose units linked together by β-1,4-glycosidic bonds. Therefore, this statement is **correct**. ### Step 2: Analyze Statement (ii) **Statement (ii)**: Inulin is a homopolymer of fructose. - **Explanation**: Inulin is a type of carbohydrate that is a homopolymer composed solely of fructose units. It is commonly found in plants and serves as a storage form of energy. Thus, this statement is also **correct**. ### Step 3: Analyze Statement (iii) **Statement (iii)**: Starch gives blue color and glycogen gives red color with iodine solution. - **Explanation**: When starch is treated with iodine solution, it produces a blue color due to the formation of a complex between iodine and the helical structure of amylose (a component of starch). Glycogen, on the other hand, can give a reddish-brown color with iodine due to its branched structure. Therefore, this statement is **correct**. ### Step 4: Analyze Statement (iv) **Statement (iv)**: Cellulose gives no color with iodine solution. - **Explanation**: Cellulose does not react with iodine to produce any color because it does not have the helical structure that iodine can interact with. Thus, this statement is also **correct**. ### Conclusion After analyzing all four statements: 1. Cellulose is a homopolymer of glucose - **Correct** 2. Inulin is a homopolymer of fructose - **Correct** 3. Starch gives blue color and glycogen gives red color with iodine solution - **Correct** 4. Cellulose gives no color with iodine solution - **Correct** Since all statements are correct, the correct answer is **Option D: All statements are correct**. ---
