Average = (Mark1 * 0.5) + (Mark2 * 0.5) so compute (74 * 0.5) + (76 * 0.5) = 37 + 38 = 75.

1) Relevant concepts:
- The script calculates the arithmetic mean by weighting each test by 0.5 (equivalent to (Mark1 + Mark2)/2).
- Conditional branching uses a top-down if / else if / else sequence. Each condition is tested in order; once a true condition is found its branch runs and the rest are skipped.
- The comparisons are strict greater-than checks ("> 75" and "> 50"), not greater-than-or-equal-to.

2) Step-by-step reasoning:
- Set Mark1 = 74, Mark2 = 76 (from input).
- Compute Average: Mark1 * 0.5 = 74 * 0.5 = 37. Mark2 * 0.5 = 76 * 0.5 = 38.
- Add them: 37 + 38 = 75, so Average = 75.

3) Evaluate conditions in order:
- First condition: if Average > 75. Here 75 > 75 is false (because it's not strictly greater).
- Because the first condition is false, move to the else part which contains: if Average > 50. Evaluate: 75 > 50 is true.
- Since this second condition is true, the script executes the "say 'Congratulations on your passing average.'" branch and then skips the final else.

4) Why the correct answer is correct:
- The average equals 75 which does not satisfy the > 75 test for the high-average message, but does satisfy > 50, so the passing-average message is shown.

5) Why the other options are incorrect:
- "No message" is wrong because one of the conditions is true and a message is displayed.
- "Unfortunately, you failed." is the else branch for Average ≤ 50, not applicable for 75.
- "Congratulations on your high average!!" would require Average > 75; 75 is not greater than 75.

Conclusion: The script will display "Congratulations on your passing average." (option a), which matches the provided answer.
