Matplotlib - Image Display

What will the following code display?

import matplotlib.pyplot as plt
import numpy as np
img = np.array([[0, 1], [1, 0]])
plt.imshow(img, cmap='gray')
plt.show()

AA 2x2 image with black and white pixels

BA line plot of the array values

CAn error because cmap='gray' is invalid

DA blank plot with no image

Step-by-Step Solution

Solution:

Step 1: Understand the array and cmap
The array has values 0 and 1 arranged in a 2x2 grid. Using cmap='gray' maps 0 to black and 1 to white.
Step 2: Predict the image output
The image will show a 2x2 grid with black and white pixels arranged as per the array.
Final Answer:
A 2x2 image with black and white pixels -> Option A
Quick Check:
Array + cmap='gray' = black/white image [OK]

Quick Trick: cmap='gray' shows 0 as black, 1 as white [OK]
