D. None of these

Explanation

To solve the given problem step by step, we will analyze the information provided and identify the compounds involved.

### Step 1: Identify Compound A
- **Given:** A is a colorless solid that, when heated, gives off a gas (B) which is a supporter of combustion.
- **Analysis:** A common colorless solid that fits this description is ammonium nitrate (NH4NO3). When heated, ammonium nitrate decomposes to produce dinitrogen oxide (N2O), which is a supporter of combustion.

**Conclusion:**
- **Compound A:** Ammonium nitrate (NH4NO3)
- **Gas B:** Dinitrogen oxide (N2O)

### Step 2: Identify Gas C
- **Given:** When A (ammonium nitrate) is heated with an aqueous NaOH solution, an alkaline gas (C) is evolved.
- **Analysis:** The reaction of ammonium nitrate with NaOH produces ammonia gas (NH3), which is alkaline in nature.

**Conclusion:**
- **Gas C:** Ammonia (NH3)

### Step 3: Identify Compound D
- **Given:** When gas B (N2O) is treated with soda amine, a colorless solid (D) is formed.
- **Analysis:** The reaction of dinitrogen oxide with sodium amide (soda amine) produces sodium azide (NaN3).

**Conclusion:**
- **Compound D:** Sodium azide (NaN3)

### Step 4: Identify Compound E
- **Given:** When compound D (sodium azide) is heated with dilute sulfuric acid (H2SO4), a colorless liquid (E) is formed.
- **Analysis:** The reaction of sodium azide with dilute sulfuric acid produces hydrazoic acid (HN3) and sodium bisulfate (NaHSO4).

**Conclusion:**
- **Compound E:** Hydrazoic acid (HN3)

### Step 5: Determine the Structure of Compound E
- **Given:** We need to find the structure of compound E (HN3).
- **Analysis:** Hydrazoic acid (HN3) has a linear structure due to the arrangement of nitrogen atoms. The structure can be represented as H-N=N=N, where the nitrogen atoms are connected in a linear fashion.

**Conclusion:**
- **Structure of Compound E:** Linear structure (H-N=N=N)

### Final Answer
- **Compound E:** Hydrazoic acid (HN3) with a linear structure.
