Answer: ```python if day_of_week == 1 and review_period:
The correct control flow statement to begin the conditionally executed code block would be D: if day_of_week == 1 and review_period:. This statement checks if the variable day_of_week is equal to 1 and if the variable review_period evaluates to a truthy value. The use of the double equal sign (==) in the comparison of day_of_week is crucial, as a single equal sign (=) would assign a value to the variable instead of checking its value. The use of the keyword and ensures proper logical comparison. The options that use quotes around True will lead to a string comparison, which is not correct in this context.

A data engineer is working on a Python program and intends to execute a specific block of code only under certain conditions. The criteria for executing this block are that the variable day_of_week must be equal to 1, and another variable, review_period, must be set to True. Given this scenario, which of the following control flow statements should the data engineer use to initiate this conditional execution of the code block?
A
if day_of_week = 1 and review_period:
if day_of_week = 1 and review_period:
B
if day_of_week = 1 and review_period = "True":
if day_of_week = 1 and review_period = "True":
C
if day_of_week == 1 and review_period == "True":
if day_of_week == 1 and review_period == "True":
D
if day_of_week == 1 and review_period:
if day_of_week == 1 and review_period:
E
if day_of_week = 1 & review_period: = "True":
if day_of_week = 1 & review_period: = "True":
