This PCEP practice question tests your understanding of control flow, loops, lists and logic. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
x = 10
y = 5
if x > 5 and y < 10:
result = 'A'
elif x == 10 or y == 5:
result = 'B'
else:
result = 'C'
print(result)Refer to the exhibit. What is printed?
x = 10
y = 5
if x > 5 and y < 10:
result = 'A'
elif x == 10 or y == 5:
result = 'B'
else:
result = 'C'
print(result)None (error)
Why wrong: No error.
A
First condition met.
B
Why wrong: Elif not evaluated because first condition is true.
C
Why wrong: Else not reached.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
A
The code uses a `for` loop to iterate over the list `['A', 'B', 'C']`. The `break` statement inside the loop executes when the variable `letter` equals `'A'`, immediately terminating the loop. Therefore, only `'A'` is printed before the loop ends, making option B correct.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
None (error)
Why it's wrong here

Common exam traps
Python Institute often tests the misconception that `break` only exits the current iteration or that the loop continues after the break, leading candidates to think multiple values are printed.
Detailed technical explanation
The `break` statement in Python immediately exits the innermost enclosing loop, skipping any remaining iterations. In this case, the loop variable `letter` takes the value `'A'` on the first iteration, the condition `letter == 'A'` is true, and `break` executes before any subsequent list elements are processed. This behavior is consistent with Python's control flow model and is commonly used to exit loops early when a target value is found, such as in linear search algorithms.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
