Choose the mis match:

Options

A. amylose contains `alpha` 1,4 glycosidic bond
B. `K^(+) rarr `most abundant mineral element in ICF
C. `Na^(+) rarr `most abundant mineral element in ECF
D. cellulose `rarr` violet colour with iodine solution

Answer

To solve the question "Choose the mismatch," we will analyze each of the provided options one by one to identify which statement is incorrect.

### Step-by-Step Solution:

1. **Option A: Amylose contains alpha 1,4 glycosidic bond.**
- Amylose is a polysaccharide that is part of starch. It is composed of glucose units linked by alpha 1,4 glycosidic bonds.
- **Conclusion:** This statement is correct.

2. **Option B: Potassium is the most abundant mineral element in the intracellular fluid.**
- Potassium (K) is indeed the most abundant cation in the intracellular fluid, playing a crucial role in cellular functions.
- **Conclusion:** This statement is correct.

3. **Option C: Sodium is the most abundant mineral element in the extracellular fluid.**
- Sodium (Na) is the most abundant cation in the extracellular fluid, essential for various physiological processes, including maintaining fluid balance and nerve transmission.
- **Conclusion:** This statement is correct.

4. **Option D: Cellulose gives a violet color with iodine solution.**
- When iodine solution is added to starch, it turns blue-black due to the coiled structure of amylose. However, cellulose, which is a linear polysaccharide, does not react with iodine and does not produce any color change.
- **Conclusion:** This statement is incorrect.

### Final Answer:
The mismatch is **Option D: Cellulose gives a violet color with iodine solution.**
