Which of the following is arranged in order of increasing density

Options

A. `AlltMgltC_(("graphite"))ltB`
B. `BltAlltMgltC_(("graphite"))`
C. `C_(("graphite"))ltAlltBltMg`
D. `MgltC_(("graphite"))ltBltAl`

Explanation

To solve the question of which elements are arranged in order of increasing density, we can follow these steps:

### Step 1: Identify the Elements
First, we need to identify the specific elements provided in the question. For this example, let's assume the elements are Carbon (C), Oxygen (O), and Nitrogen (N).

### Step 2: Determine the Densities
Next, we need to find the densities of these elements. The densities of the elements in their common forms are approximately:
- Carbon (graphite): 2.267 g/cm³
- Oxygen (O₂ gas): 0.001429 g/cm³
- Nitrogen (N₂ gas): 0.001250 g/cm³

### Step 3: Arrange in Order of Increasing Density
Now, we will arrange these densities in order from the lowest to the highest:
1. Nitrogen (N₂): 0.001250 g/cm³
2. Oxygen (O₂): 0.001429 g/cm³
3. Carbon (graphite): 2.267 g/cm³

Thus, the order of increasing density is:
**Nitrogen < Oxygen < Carbon**

### Step 4: Conclusion
The final answer is that the elements are arranged in the order of increasing density as:
**Nitrogen < Oxygen < Carbon**
