Let's break down the pseudocode to determine the output:

### Initial Setup:
- `Integer J` is declared but not initialized, so it doesn't affect the computation.
- `Integer arr[4] = (0, 9, 10, 2)` initializes an array `arr` with four values: 0, 9, 10, and 2.

### Step 4:
- The pseudocode seems to be incomplete, but if it implies `arr[] = arr[2] + arr[0]`, then it means an operation on `arr`. Specifically, `arr[2] + arr[0]` would be:
  \[
  arr[2] + arr[0] = 10 + 0 = 10
  \]
  It's unclear where this value is stored, so we move on assuming this step doesn't change the array.

### Step 5:
- The condition `1 ne ((arr[z] + arr[beta]) > (arr[z] + arr[3]))` is also unclear because `z` and `beta` are not initialized. Therefore, this condition does not affect the code logic in a meaningful way unless `z` and `beta` are defined elsewhere, which they are not in the given pseudocode.

### Step 6:
- `arr[3] = (arr[3] & 7) ^ arr[2]`: Let's calculate this step.
  - `arr[3] = 2`
  - `arr[2] = 10`
  - First, compute the bitwise AND of `arr[3]` and 7: 
    \[
    arr[3] & 7 = 2 & 7 = 2 \quad \text{(binary: 0010 \& 0111 = 0010)}
    \]
  - Now, perform the bitwise XOR with `arr[2]`:
    \[
    2 ^ 10 = 0010 \oplus 1010 = 1000 = 8
    \]
  So, `arr[3]` becomes 8 after this operation.

### Step 8:
- Print `arr[1] + arr[2]`:
  - `arr[1] = 9`
  - `arr[2] = 10`
  - The sum is:
    \[
    arr[1] + arr[2] = 9 + 10 = 19
    \]

### Conclusion:
The output of the pseudocode is **C. 19**.
