MATLAB - 3D Plotting and Visualization

What is wrong with this MATLAB code for plotting a 3D surface?

[X,Y] = meshgrid(-2:2, -2:2);
Z = X.^2 + Y.^2;
surf(X, Z);

Asurf requires three arguments: X, Y, and Z.

Bmeshgrid is used incorrectly.

CZ calculation is invalid.

Dsurf cannot plot squared values.

Step-by-Step Solution

Solution:

Step 1: Check surf function arguments
surf requires X, Y, and Z matrices to plot a 3D surface properly.
Step 2: Identify missing argument
The code passes only X and Z, missing Y, causing an error.
Final Answer:
surf requires three arguments: X, Y, and Z. -> Option A
Quick Check:
surf needs X, Y, Z inputs [OK]

Quick Trick: Always provide X, Y, and Z to surf for 3D plots [OK]
