[Solved] Identify the error in this MATLAB code:plot(1:4, [10 20 30 40]);title('Sales Data');xlabel('Month');legend('Sales'); | MATLAB

MATLAB - 2D Plotting

Identify the error in this MATLAB code:

plot(1:4, [10 20 30 40]);
title('Sales Data');
xlabel('Month');
legend('Sales');

AMissing ylabel() for y-axis label

BNo error, code is correct

Clegend() called with only one label for one line

Dxlabel() should be ylabel()

Step-by-Step Solution

Solution:

Step 1: Verify each line of code
plot() creates the plot, title() adds title, xlabel() labels x-axis, legend('Sales') correctly labels the single plotted line.
Step 2: Confirm no syntax or logical errors
All functions are used correctly; missing ylabel() is optional and does not cause an error.
Final Answer:
No error, code is correct -> Option B
Quick Check:
Single line plot with legend('Sales') runs fine [OK]

Quick Trick: legend('label') is valid for single plots [OK]
