MATLAB - 2D Plotting

values = [10 20 30 40];
bar(values, 'red');

AThe code is correct and will produce a red bar chart

Bbar function does not accept vectors as input

CThe color 'red' is not a valid color in MATLAB

DThe color should be specified using a name-value pair, not as a second argument

Step-by-Step Solution

Solution:

Step 1: Check bar function syntax for color
Color must be set using name-value pairs like bar(values, 'FaceColor', 'red').
Step 2: Validate other options
bar accepts vectors; 'red' is valid color; code will error due to wrong argument usage.
Final Answer:
The color should be specified using a name-value pair, not as a second argument -> Option D
Quick Check:
Color must be set with name-value pairs = D [OK]

Quick Trick: Use name-value pairs to set bar colors [OK]
