C. `1296`
D. `864`

Explanation

To find the number of males employed in the HR company who are younger than 25 years, we can follow these steps:

### Step 1: Calculate the total number of males in the company.
Given that the company employs a total of 4800 people and 45% of them are males, we can calculate the number of males as follows:

\[ \text{Number of males} = 45\% \text{ of } 4800 = \frac{45}{100} \times 4800 \]

Calculating this gives:

\[ \text{Number of males} = 0.45 \times 4800 = 2160 \]

### Step 2: Calculate the number of males who are 25 years or older.
Next, we know that 60% of the males are 25 years or older. We can calculate this number:

\[ \text{Number of males 25 years or older} = 60\% \text{ of } 2160 = \frac{60}{100} \times 2160 \]

Calculating this gives:

\[ \text{Number of males 25 years or older} = 0.60 \times 2160 = 1296 \]

### Step 3: Calculate the number of males who are younger than 25 years.
To find the number of males who are younger than 25 years, we subtract the number of males who are 25 years or older from the total number of males:

\[ \text{Number of males younger than 25 years} = \text{Total males} - \text{Males 25 years or older} \]

Substituting the values we calculated:

\[ \text{Number of males younger than 25 years} = 2160 - 1296 = 864 \]

### Final Answer:
The number of males employed in the HR company who are younger than 25 years is **864**.
