Matplotlib - Image Display

What will be the output when running this code?

import matplotlib.pyplot as plt
import numpy as np
img = np.zeros((3,3))
plt.imshow(img, cmap='gray')
plt.colorbar()
plt.show()

AA 3x3 white image with no colorbar

BAn error because <code>cmap</code> is invalid

CA 3x3 black image with a grayscale colorbar

DA 3x3 colored image with random colors

Step-by-Step Solution

Solution:

Step 1: Understand the image data
np.zeros((3,3)) creates a 3x3 array of zeros, representing black pixels in grayscale.
Step 2: Analyze plotting commands
plt.imshow(img, cmap='gray') displays the image in grayscale, and plt.colorbar() adds a color scale bar.
Final Answer:
A 3x3 black image with a grayscale colorbar -> Option C
Quick Check:
Zero array + grayscale cmap = black image with colorbar [OK]

Quick Trick: Zeros array with gray cmap shows black image [OK]
