Let's solve this step by step.

### Problem Breakdown:
- The oil spill covers **4 square kilometers** in **1/4 of an hour**.
- We need to determine how much area it will cover in **2 hours** if it continues at the same rate.

### Step 1: Calculate the rate per hour.
- If the spill covers **4 square kilometers** in **1/4 hour**, we multiply by **4** to find the rate per hour:
  \[
  4 \, \text{square kilometers} \times 4 = 16 \, \text{square kilometers per hour}.
  \]
  
### Step 2: Calculate the amount for 2 hours.
- Now, if the rate is **16 square kilometers per hour**, we multiply it by **2 hours**:
  \[
  16 \, \text{square kilometers per hour} \times 2 \, \text{hours} = 32 \, \text{square kilometers}.
  \]

### Final Answer:
The oil spill will cover **32 square kilometers** in 2 hours. 

The correct option is:
- **32 square kilometers**
