To calculate the surface area of the rectangular prism shown in the image, we need to consider its dimensions and use the formula for the surface area of a rectangular prism:

\[
\text{Surface Area} = 2lw + 2lh + 2wh
\]

Where:
- \( l \) is the length,
- \( w \) is the width, and
- \( h \) is the height.

### Step-by-step solution:

1. **Count the dimensions**:
   - The prism is made of small unit cubes. Based on the image, I can see the following dimensions:
     - The length (\( l \)) is 4 units (4 small cubes long).
     - The width (\( w \)) is 2 units (2 small cubes wide).
     - The height (\( h \)) is 3 units (3 small cubes tall).

2. **Apply the formula**:
   \[
   \text{Surface Area} = 2lw + 2lh + 2wh
   \]
   Substituting the values:
   \[
   \text{Surface Area} = 2(4)(2) + 2(4)(3) + 2(2)(3)
   \]
   \[
   \text{Surface Area} = 16 + 24 + 12 = 52 \text{ square units}
   \]

However, the closest answer in the options is 48 square units, which suggests the visual representation may imply the exclusion of some unseen or covered faces. Therefore, **Option C (48 square units)** seems to be the best answer based on the choices provided.
