Correct Answer: D

Explanation:

1. Option A and D are identical - Both use the correct syntax if day_of_week == 1 and review_period:
2. Option B is incorrect because it uses a single equal sign (=) which is assignment, not comparison
3. Option C is incorrect because it compares review_period to the string "True" instead of the boolean value True
4. Option E is incorrect because it uses the bitwise AND operator (&) instead of the logical AND keyword (and), and also incorrectly compares to the string "True"

Key Python Concepts:

• Use == for equality comparison, not = (which is for assignment)
• Use and for logical AND operations, not & (which is bitwise AND)
• Boolean values in Python are True and False (without quotes), not strings "True" or "False"
• When checking if a boolean variable is True, you can simply use the variable name in the condition (e.g., if review_period:)

Note: Since both A and D are identical and correct, but the provided answer indicates D, we follow the given answer. In practice, both A and D would be correct answers.
