Database Fundamentals — Question 116

This question requires that you evaluate the underlined text to determine if it is correct.
A key defines the amount of storage space that is allocated to a value in a column.
Instructions: Review the underlined text. If it makes the statement correct, select "No change is needed." If the statement is incorrect, select the answer choice that makes the statement correct

Answer options

• A. No change is needed
• B. format
• C. data type
• D. validator

Correct answer: C

Explanation

The correct answer is C, 'data type', because a data type specifies the kind of data that can be stored in a column and how much space it requires. The term 'key' does not relate to storage allocation; therefore, options A, B, and D do not properly correct the statement.
