Matplotlib - 3D Plotting

Identify the error in this code snippet for a 3D wireframe plot:

import numpy as np
import matplotlib.pyplot as plt
fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')
X = np.linspace(-3, 3, 10)
Y = np.linspace(-3, 3, 10)
Z = np.sin(X) * np.cos(Y)
ax.plot_wireframe(X, Y, Z)
plt.show()

AX and Y should be lists, not arrays

BMissing import for Axes3D

Cplot_wireframe does not exist

DZ is not a 2D array matching X and Y meshgrid shape

Step-by-Step Solution

Solution:

Step 1: Check shapes of X, Y, and Z
X and Y are 1D arrays; Z is computed element-wise but is also 1D, not 2D grid.
Step 2: Understand plot_wireframe requirements
plot_wireframe requires X, Y, Z to be 2D arrays from meshgrid to plot a surface grid.
Final Answer:
Z is not a 2D array matching X and Y meshgrid shape -> Option D
Quick Check:
plot_wireframe needs 2D X, Y, Z arrays [OK]

Quick Trick: Use meshgrid to make X, Y, Z 2D arrays for wireframe [OK]

Common Mistakes:

Passing 1D arrays instead of meshgrid 2D arrays
Ignoring shape mismatch errors
Assuming plot_wireframe works with 1D inputs
