What will be the output of this code snippet?

import matplotlib.pyplot as plt
before = [5, 7]
after = [8, 6]
plt.plot([1, 2], before, label='Before')
plt.plot([1, 2], after, label='After')
plt.legend()
plt.show()

AAn error because plt.plot cannot take two lists

BA bar chart comparing before and after data

CA scatter plot with points at (1,5), (2,7), (1,8), (2,6)

DTwo overlapping line plots showing before and after data

Step-by-Step Solution

Solution:

Step 1: Understand plt.plot with x and y lists
plt.plot([1, 2], before) plots points (1,5) and (2,7) connected by a line. Similarly for after data.
Step 2: Identify plot type and legend
Two line plots will appear overlapping on the same axes with labels 'Before' and 'After'. No error occurs.
Final Answer:
Two overlapping line plots showing before and after data -> Option D
Quick Check:
plt.plot with x,y lists = line plot [OK]

Quick Trick: plt.plot(x, y) draws lines connecting points [OK]

Common Mistakes:

Thinking plt.plot creates bar charts
Expecting scatter plot without plt.scatter
Assuming plt.plot with two lists causes error
