NumPy - Creating Arrays

The code below throws an error. What is the mistake?

import numpy as np
matrix = np.eye(4, 3, k=4)
print(matrix)

Anp.eye() does not accept three arguments

BThe matrix must be square for np.eye()

CThe value of k is too large for the matrix shape

DThe print statement is incorrect

Step-by-Step Solution

Solution:

Step 1: Check the meaning of k relative to matrix size
The parameter k=4 means the diagonal of 1s is shifted 4 above the main diagonal.
Step 2: Compare k with matrix dimensions
For a 4x3 matrix, the maximum upper diagonal shift is 2 (columns - 1). k=4 is invalid and causes an error.
Final Answer:
The value of k is too large for the matrix shape -> Option C
Quick Check:
k must be within valid diagonal range [OK]

Quick Trick: k must fit within matrix diagonal limits [OK]
