Matplotlib - Interactive Features

What is wrong with this interactive plot code?

import matplotlib.pyplot as plt
plt.ion()
fig, ax = plt.subplots()
ax.plot([1, 2, 3], [1, 4, 9])
plt.show()
ax.set_title('My Plot')

Aplt.ion() disables plot display

Bfig, ax = plt.subplots() is invalid syntax

Cax.plot() must be called after plt.show()

DThe title is set after plt.show(), so it won't appear

Step-by-Step Solution

Solution:

Step 1: Understand plt.show() effect
plt.show() displays the plot and blocks further changes in non-interactive mode.
Step 2: Analyze timing of set_title call
Setting title after plt.show() means the title change may not update on the displayed plot.
Final Answer:
The title is set after plt.show(), so it won't appear -> Option D
Quick Check:
Plot update timing = Set title before plt.show() [OK]

Quick Trick: Set plot titles before plt.show() to ensure visibility [OK]
