To answer this question, let's go through each option to understand why it is correct or incorrect:
Option A) output on the terminal: result = 2 3 5 - This option is incorrect because the program will not reach this line of code. The correct answer indicates that the program will terminate with an error.
Option B) output on the terminal: result = 3 2 1 - This option is incorrect because the program will not reach this line of code. The correct answer indicates that the program will terminate with an error.
Option C) output on the terminal: result = var_3 var_4 var_5 - This option is incorrect because the program will not reach this line of code. The correct answer indicates that the program will terminate with an error.
Option D) the program will terminate with an error - This option is correct because the program encounters an error in the IF-THEN-ELSE statement. The condition "var_1 = var_2" evaluates to false, so the program executes the statements in the ELSE block. However, there is no statement to assign values to the variables var_3, var_4, and var_5 in the ELSE block. Therefore, the program will terminate with an error.
The correct answer is D. The program will terminate with an error.
