D. The reaction is known as Schmidt rearrangement reaction.

Explanation

To analyze the reaction provided in the question, we will break it down step by step, focusing on the transformation of benzoic acid (PhCOOH) through the specified reactions.

### Step 1: Identify the Reactants
The starting compound is benzoic acid (PhCOOH).

### Step 2: First Reaction with N2H4 in Acidic Medium
In the first step, benzoic acid reacts with hydrazine (N2H4) in an acidic medium (H⁺). This reaction typically leads to the formation of a hydrazone derivative. The hydroxyl group (OH) from the carboxylic acid and a hydrogen (H) from hydrazine combine to form water (H2O), resulting in the formation of a new compound.

**Formation of Compound B:**
- The reaction can be summarized as:
\[ \text{PhCOOH} + \text{N}_2\text{H}_4 \xrightarrow{H^+} \text{Compound B} \]

### Step 3: Heating the Product
Next, the product (Compound B) is heated. During this step, a rearrangement occurs where nitrogen leaves the structure, potentially leading to the formation of an intermediate compound.

### Step 4: Rearrangement Reaction
The rearrangement that occurs is known as the Claisen-Bischoff rearrangement. In this reaction, the phenyl group (Ph) attacks the nitrogen, leading to the formation of a new compound.

**Formation of Compound C:**
- The reaction can be summarized as:
\[ \text{Compound B} \xrightarrow{\Delta} \text{Compound C} \]

### Step 5: Reaction with Water in Basic Medium
Finally, Compound C is treated with water in a basic medium (OH⁻). This leads to the hydrolysis of the compound, resulting in the formation of aniline (PhNH2) and the release of carbon dioxide (CO2).

### Conclusion
The final products of the reaction sequence are:
- Compound B: An intermediate formed after the first reaction.
- Compound C: Aniline (PhNH2).

### Summary of Statements
1. **Statement A**: Correct, as it describes the formation of Compound B and C accurately.
2. **Statement B**: Incorrect, as it mentions wrong products.

### Final Answer
The correct answer will be the statements that accurately describe the reaction and products formed.
