The error introduced in the code is that the condition for checking if the temperature is between 15°C and 20°C is incorrect. Identify and fix the error in the provided MATLAB code? temperature = input('Enter the temperature: '); % Check temperature conditions if temperature > 40 disp('Temperature is above 40°C. Switching on the air conditioner.'); % Code to switch on the air conditioner elseif temperature >= 15 && temperature < 20 disp('Temperature is between 15°C and 20°C. Switching off the air conditioner and switching on the fan.'); % Code to switch off the air conditioner and switch on the fan else disp('Temperature is below 15°C. Switching on the heater.'); % Code to switch on the heater end

A) Change `temperature >= 15 && temperature < 20` to `temperature >= 15 && temperature <= 20`

B) Change `temperature >= 15 && temperature < 20` to `temperature > 15 && temperature < 20`

C) Change `temperature >= 15 && temperature < 20` to `temperature > 15 || temperature < 20

D) Change `temperature >= 15 && temperature < 20` to `temperature <= 15 && temperature > 20`

Identify and fix the error in the provided MATLAB program. array = [1, 2, 3, 4, 5]; sum = 0; for i = 1:length(array) sum = sum + array[i]; % Error: Incorrect indexing of array elements end disp(['The sum of elements in the array is: ', num2str(sum)]);

A) Replace `array[i]` with `array(i)` in the loop.

B) Replace `length(array)` with `size(array, 1)` to get the number of rows.

C) Change `sum = 0` to `sum = [ ]` to initialize sum as an empty array.

D) Remove the loop and directly calculate the sum using the `sum()` function

What error is present in the given MATLAB program, and how can it be fixed? length = input('Enter the length of the rectangle: '); width = input('Enter the width of the rectangle: '); area = length * width; disp(['The area of the rectangle is: ', area]);

A) The program will result in a syntax error due to the incorrect use of quotation marks in the `disp` function.

B) The program will result in a runtime error due to using the variable `area` without converting it to a string in the `disp` function.

D) The program will result in a runtime error due to missing semicolons after each statement.

What does the following MATLAB code snippet do? arr = [1, 2, 3, 4, 5]; arr(3) = 10;
