Matplotlib - 3D Plotting

What is wrong with this matplotlib code for a 3D scatter plot?

import matplotlib.pyplot as plt
fig = plt.figure()
ax = fig.add_subplot(111)
ax.scatter([1,2], [3,4], [5,6])
plt.show()

AThe subplot lacks the 'projection="3d"' argument

BThe scatter method cannot take three lists as input

Cplt.figure() should be plt.plot()

DThe lists have different lengths

Step-by-Step Solution

Solution:

Step 1: Check subplot creation
The subplot is created without specifying 3D projection, so it defaults to 2D.
Step 2: Understand scatter inputs
Scatter can accept three lists for 3D plots, but only if the axis supports 3D.
Final Answer:
The subplot lacks the 'projection="3d"' argument -> Option A
Quick Check:
Always add projection='3d' for 3D plots [OK]

Quick Trick: Add projection='3d' to subplot for 3D plots [OK]
