Matplotlib - Image Display

You want to display a 2D numpy array as an image but only show pixel values between 50 and 200. Which imshow parameters help achieve this?

AUse <code>cmap='gray'</code> only

BUse <code>interpolation='nearest'</code> only

CResize the array to values between 50 and 200 before imshow

DUse <code>vmin=50</code> and <code>vmax=200</code> in imshow

Step-by-Step Solution

Solution:

Step 1: Understand vmin and vmax
These parameters set the data value range mapped to the colormap.
Step 2: Confirm other options
cmap changes colors but not value range; resizing data is manual; interpolation affects pixel smoothing.
Final Answer:
Use vmin=50 and vmax=200 in imshow -> Option D
Quick Check:
vmin/vmax control displayed data range [OK]

Quick Trick: Set vmin and vmax to clip displayed pixel values [OK]
