Which one of the following is a heterogenous mixture ?

Options

A. Starch
B. Dextrin
C. Glycogen
D. Gum arabic

Answer

To determine which of the given options is a heterogeneous mixture, we will analyze each option one by one.

### Step 1: Understanding Heterogeneous Mixtures
A heterogeneous mixture is a type of mixture where the components can be visibly distinguished and are not uniformly distributed. In contrast, homogeneous mixtures have a uniform composition throughout.

### Step 2: Analyzing the Options
1. **Starch**: Starch is a polysaccharide that is generally considered a homogeneous mixture when dissolved in water, forming a colloidal solution.

2. **Dextrin**: Dextrin is also a carbohydrate that can dissolve in water, forming a homogeneous solution.

3. **Glycogen**: Glycogen is a polysaccharide that is stored in the body and is also soluble in water, making it a homogeneous mixture.

4. **Gum Arabic**: Gum Arabic is a natural gum made of polysaccharides and glycoproteins. When mixed with water, it does not dissolve completely and can form a heterogeneous mixture where fat particles may be suspended in the water.

### Step 3: Conclusion
Based on the analysis above, the only option that qualifies as a heterogeneous mixture is **Gum Arabic**.

### Final Answer
**Gum Arabic** is a heterogeneous mixture.
