What will happen when this code is executed?

import matplotlib.pyplot as plt
import matplotlib
matplotlib.use('TkAgg')
plt.plot([1, 2, 3], [4, 5, 6])
plt.show()

AThe plot is saved to a file named 'plot.png'

DNothing happens; the script runs silently

Step-by-Step Solution

Solution:

Step 1: Import pyplot before setting backend
Backend must be set before importing pyplot to take effect.
Step 2: Setting backend after pyplot import
This causes a runtime error because backend is already initialized.
Step 3: plt.show() call
This will not execute properly due to the prior error.
Final Answer:
An error occurs due to backend set after pyplot import -> Option C
Quick Check:
Set backend before importing pyplot [OK]

Quick Trick: Always set backend before importing pyplot [OK]
