D. `(-)` 2, 3-dibromosuccinic acid

Explanation

To solve the problem of the reaction between maleic acid and bromine in the presence of carbon tetrachloride (CCl4), we can follow these steps:

### Step 1: Understand the Structure of Maleic Acid
Maleic acid is a dicarboxylic acid with the following structure:
- It has two carboxylic acid groups (-COOH) and a double bond between two carbon atoms.
- The structure can be represented as:

```
HOOC-CH=CH-COOH
```

### Step 2: Identify the Reaction Conditions
The reaction takes place in the presence of bromine (Br2) and carbon tetrachloride (CCl4). CCl4 is used as a solvent that does not participate in the reaction.

### Step 3: Mechanism of the Reaction
1. The double bond in maleic acid will react with bromine. The π electrons of the double bond will attack a bromine molecule (Br2), leading to the formation of a bromonium ion.
2. The bromonium ion is a cyclic structure where one bromine atom is positively charged and attached to one of the carbon atoms of the double bond.

### Step 4: Formation of Products
1. The bromonium ion can be attacked by a bromide ion (Br-) at either of the two carbon atoms involved in the double bond.
2. This leads to the formation of two different products due to the possibility of bromine attacking from either side of the bromonium ion.

### Step 5: Draw the Products
The two products formed can be represented as:
- Product 1:

```
HOOC-CHBr-CHBr-COOH
```

- Product 2:

```
HOOC-CHBr-CHBr-COOH
```

### Step 6: Analyze the Stereochemistry
1. Both products are stereoisomers and will have different configurations at the carbon atoms where bromine is attached.
2. Since the two products are formed in equal amounts, they will create a racemic mixture (equal amounts of both enantiomers).

### Step 7: Naming the Products
The products can be named as:
- 2,3-dibromosuccinic acid, since the original maleic acid is transformed into succinic acid with two bromine substituents.

### Final Answer
The reaction of maleic acid with Br2 in CCl4 produces a racemic mixture of 2,3-dibromosuccinic acid.
