Final answer:
The 'Solution' column will contain the number '8', as DATEPART(month, RegistrationDate) extracts the month part of the date as an integer.
Step-by-step explanation:
If the RegistrationDate contains a value that’s equivalent to August 10, 2016, when the code DATEPART(month, RegistrationDate) AS Solution is executed, the Solution column will contain the integer 8. This is because the DATEPART function in SQL is used to extract a specific part of a date, such as the day, month, or year, from a date field. In this instance, DATEPART(month, RegistrationDate) is used to extract the month part of the RegistrationDate field, which is August, the eighth month of the year. Therefore, the function will return the number of the month, not the name, so the correct answer is b.8.
