Assume X, Y, Z, W and P are matrices of order `2 xxn`, `3 xxk`, `2 xxp`, `n xx3`and `p xxk`, respectively. Choose the correct answer
The restriction on n, k and p so that `P Y + W Y`will be defined are:(A) `k = 3, p = n` (B) `k` is arbitrary, `p=2` (C) `p` is arbitrary, `k=3` (D) `k=2`, `p=3`

Explanation

To solve the problem, we need to determine the conditions under which the expression \( PY + WY \) is defined, given the orders of the matrices involved.

### Step-by-Step Solution:

1. **Identify the Orders of the Matrices:**
- \( P \) is of order \( p \times k \)
- \( Y \) is of order \( 3 \times k \)
- \( W \) is of order \( n \times 3 \)
