Which of the following is the correct way to import and apply a Gaussian filter with sigma=2 to a 2D numpy array named image?

Afrom scipy.ndimage import gaussian_filter filtered = gaussian_filter(image, sigma=2)

Bimport scipy filtered = scipy.gaussian_filter(image, 2)

Cfrom scipy import gaussian_filter filtered = gaussian_filter(image, 2)

Dimport gaussian_filter from scipy.ndimage filtered = gaussian_filter(image, sigma=2)

Step-by-Step Solution

Solution:

Step 1: Check the correct import statement
The Gaussian filter is in scipy.ndimage, so import it with from scipy.ndimage import gaussian_filter.
Step 2: Verify function usage
Apply it by calling gaussian_filter(image, sigma=2) to blur with sigma 2.
Final Answer:
from scipy.ndimage import gaussian_filter filtered = gaussian_filter(image, sigma=2) -> Option A
Quick Check:
Correct import and sigma usage = from scipy.ndimage import gaussian_filter filtered = gaussian_filter(image, sigma=2) [OK]

Quick Trick: Import from scipy.ndimage, use sigma as keyword [OK]
