Explanation

To determine the correct IUPAC name of the given compound, we will follow these steps:

### Step 1: Identify the structure
The compound has a carbon chain with various substituents. The structure can be interpreted as:
- A four-carbon chain (butane) with the following substituents:
- A bromo (Br) group
- A fluoro (F) group
- An iodo (I) group
- A nitro (NO₂) group

### Step 2: Number the carbon chain
To assign the correct numbers to the substituents, we need to number the carbon chain. The numbering should start from the end closest to the first substituent encountered:
- Start numbering from the right:
- Carbon 1: Iodo (I)
- Carbon 2: Bromo (Br)
- Carbon 3: Nitro (NO₂)
- Carbon 4: Fluoro (F)

### Step 3: Assign locants to substituents
Based on the numbering:
- Carbon 1: Iodo
- Carbon 2: Bromo
- Carbon 3: Nitro
- Carbon 4: Fluoro

### Step 4: Write the substituents in alphabetical order
When writing the IUPAC name, substituents are listed in alphabetical order, regardless of their locants:
- Bromo (Br)
- Fluoro (F)
- Iodo (I)
- Nitro (NO₂)

### Step 5: Combine the substituents with the parent chain
Now we can put together the substituents with their locants and the parent chain:
- The parent chain is butane (4 carbon atoms).
- The substituents in order are: 2-bromo, 4-fluoro, 1-iodo, and 3-nitro.

### Final IUPAC Name
Combining all the information, the correct IUPAC name of the compound is:
**2-bromo-4-fluoro-1-iodo-3-nitrobutane**
