C. triamminechlorobromonitroplatinum (IV) chloride
D. triamminenitrochlorobromoplatinum (IV) chloride

Explanation

To find the IUPAC name of the coordination compound \([Pt(NH_3)_3(Br)(NO_2)Cl]Cl\), we will follow a systematic approach.

### Step-by-Step Solution:

1. **Identify the Coordination Complex**:
The coordination complex is \([Pt(NH_3)_3(Br)(NO_2)Cl]^+\). The outer chloride ion is a counter ion.

2. **Determine the Oxidation State of Platinum (Pt)**:
Let the oxidation state of platinum be \(x\).
- The amine ligands (NH3) are neutral, contributing 0.
- The bromido (Br) is a -1 ligand.
- The nitrito (NO2) is a -1 ligand.
- The chlorido (Cl) is a -1 ligand.
- The overall charge of the coordination complex is +1.

The equation can be set up as:
\[ x + 3(0) + (-1) + (-1) + (-1) = +1 \]
Simplifying this gives:
\[ x - 3 = 1 \implies x = 4 \]
Therefore, the oxidation state of platinum is +4.

3. **Name the Ligands**:
- The amine ligand is named "ammine".
- The bromido ligand is named "bromo".
- The nitrito ligand is named "nitro" (since it is in the nitro form).
- The chlorido ligand is named "chloro".

4. **Arrange the Ligands Alphabetically**:
When naming coordination compounds, ligands are listed in alphabetical order regardless of their quantity:
- "ammine" (A)
- "bromo" (B)
- "chloro" (C)
- "nitro" (N)

Therefore, the order will be: "ammine", "bromo", "chloro", "nitro".

5. **Construct the Name of the Coordination Complex**:
Combine the names of the ligands with their respective prefixes (tri- for three ammine ligands):
- "triammine"
- "bromo"
- "chloro"
- "nitro"

Thus, the coordination part is named: **triamminobromochloronitro**.

6. **Name the Central Metal and its Oxidation State**:
The central metal is platinum, and since its oxidation state is +4, we denote it as "platinum(IV)".

7. **Combine Everything**:
Finally, we combine the names of the ligands and the metal with the counter ion:
- The complete name of the complex is: **triamminobromochloronitroplatinum(IV) chloride**.

### Final Answer:
The IUPAC name of \([Pt(NH_3)_3(Br)(NO_2)Cl]Cl\) is **triamminobromochloronitroplatinum(IV) chloride**.
