What is the actual result produced by the pseudocode if 50 was input as test data?

The conditional reads: If ExamScore >= 50 Then Print "Fail" Else Print "Pass". Evaluating the condition with the test input produces the output.

1) Relevant knowledge points and concepts
- Comparison operator >= returns true when the left operand is greater than or equal to the right operand.
- An if/else structure executes the then-branch when the condition is true, otherwise the else-branch.
- The pseudocode prints only the specified strings ("Fail" or "Pass"), not the numeric score.

2) Step-by-step reasoning
- Assign ExamScore = 50 (given test data).
- Evaluate the condition: ExamScore >= 50.

3) Intermediate calculation / evaluation
- 50 >= 50 evaluates to true (because 50 is equal to 50).

4) Branch selection and output
- Because the condition is true, the program executes the Then branch and prints "Fail".
- The Else branch ("Pass") is not executed.

5) Why the correct answer is correct
- The code explicitly treats scores greater than or equal to 50 as a failing case. Since 50 meets the >= 50 test, the program prints "Fail". This is a logical mistake relative to the expected behavior (normally >= 50 would indicate pass), but it is what the pseudocode actually does.

6) Why the other options are incorrect
- "a. Error": there is no syntax or runtime error in the shown pseudocode; it cleanly evaluates and prints a string.
- "b. Pass": would be printed only if the condition were false; but 50 >= 50 is true, so "Pass" is not printed.
- "c. 50": the pseudocode never prints the numeric score; it only prints the words "Fail" or "Pass".

Conclusion: Evaluating the condition with ExamScore = 50 yields true, so the pseudocode prints "Fail". The actual result is d. Fail.
