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 restrictions on the matrices \( P \), \( Y \), and \( W \) such that the expression \( PY + WY \) is defined.

### Step-by-step Solution:

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