To solve this question, the user needs to know what a null value is and how arithmetic expressions are evaluated.
A null value is a value that represents an absence of a value or an unknown value. In arithmetic expressions, null values can occur when a value is missing or undefined.
Now, let's go through each option and explain why it is right or wrong:
A. True: This option is incorrect. Arithmetic expressions containing a null value do not necessarily evaluate to null. The actual result depends on the specific operation being performed and the other values in the expression.
B. False: This option is correct. Arithmetic expressions containing a null value do not necessarily evaluate to null. The actual result depends on the specific operation being performed and the other values in the expression.
