import matplotlib.pyplot as plt
values = [50, 20, 30]
labels = ['A', 'B', 'C']
plt.barh(labels, values)
plt.gca().invert_yaxis()
plt.show()

AA horizontal bar chart with 'C' at the top and 'A' at the bottom

BA vertical bar chart with bars labeled A, B, C

CA horizontal bar chart with 'A' at the top and 'C' at the bottom

DAn error because invert_yaxis() is invalid here

Step-by-Step Solution

Solution:

Step 1: Understand horizontal bar chart with invert_yaxis()
The barh function plots horizontal bars with labels on y-axis. By default, y-axis starts from bottom.
Step 2: Effect of invert_yaxis()
Calling invert_yaxis() flips the y-axis so the first label 'A' appears at the top, making ranking easier to read.
Final Answer:
A horizontal bar chart with 'A' at the top and 'C' at the bottom -> Option C
Quick Check:
invert_yaxis flips labels top-down [OK]

Quick Trick: invert_yaxis() flips bars so top label is first [OK]
