Matplotlib - Image Display

What is wrong with this code?

import matplotlib.pyplot as plt
import numpy as np
image = np.array([[0, 1], [2, 3]])
plt.imshow(image, cmap='jet')
plt.colorbar
plt.show()

AThe image array contains invalid values

BThe 'jet' colormap is deprecated and cannot be used

Cplt.colorbar is missing parentheses, so colorbar won't display

Dplt.show() should come before plt.colorbar()

Step-by-Step Solution

Solution:

Step 1: Check plt.colorbar usage
plt.colorbar is a function and must be called with parentheses to display the colorbar.
Step 2: Confirm impact of missing parentheses
Without parentheses, no colorbar appears, but no error is raised.
Final Answer:
plt.colorbar is missing parentheses, so colorbar won't display -> Option C

Call plt.colorbar() with () to show colorbar [OK]

Quick Trick: Always use plt.colorbar() with parentheses [OK]
