Which check does the function check_numeric_value perform?

• A. Check if the value is an integer
• B. Check if the value is numeric using isdigit
• C. Check if the value is non-negative
• D. Check if the value is a string

Answer: (A)

The function check_numeric_value is validating that the input is an integer. The name implies a type check for whole numbers, so it’s about confirming the value is an integer type, not a string or a non-integer numeric form. Using a method like isdigit would apply to strings and check characters, not the numeric type itself, and adding constraints like non-negativity would introduce a different requirement not suggested by the name. Likewise, requiring the value to be a string contradicts the idea of it being a numeric value. So the best fit is that the function checks for an integer.
