Matplotlib - Image Display

Which data type can imshow directly display as an image?

AA Python list of strings

BA 2D numpy array representing pixel intensities

CA single integer value

DA dictionary of key-value pairs

Step-by-Step Solution

Solution:

Step 1: Identify valid input types for imshow
imshow expects 2D arrays (or 3D for color) representing pixel data.
Step 2: Eliminate invalid types
Lists of strings, single integers, or dictionaries cannot represent image pixels directly.
Final Answer:
A 2D numpy array representing pixel intensities -> Option B
Quick Check:
imshow input = 2D array [OK]

Quick Trick: Use 2D arrays for grayscale images in imshow [OK]
