Question restatement: A function that can only work on numeric fields is which of the following?

Option 1: AVERAGE
- This function computes the mean of numeric values. It inherently operates on numbers and typically ignores non-numeric entries or signals an error if the input isn’t numeric. In many data tools, AVERAGE is applied to a range containing numbers and yields a numeric result representing the average. This aligns with the idea of a function that requires numeric data to produce a meaningful numeric outcome.

Option 2: AND
- The AND function is a logical operator that combines boolean conditions. It is not restricted to numeric data; it evaluates true or false based on logical expressions. Its applicability is not tied to numeric fields specifically, so it doesn’t fit the description of a function that can only operate on numeric values.

Option 3: ISNUMBER
- ISNUMBER checks whether an input is numeric and returns a boolean result. While it focuses on numeric inputs, it is a type-checking function rather than a function that processes numeric data to produce a numeric result. It does not perform a computation on the numbers themselves, so saying it "works on numeric fields" is less about computation on numbers and more about validation.

Option 4: CONCATENATE
- CONCATENATE combines text strings. While many tools can coerce numbers to text, the primary purpose of CONCATENATE is to join strings, not to operate exclusively on numeric fields. Therefore, it is not the function that is defined by operating only on numeric data.

Synthesis: Among the options, AVERAGE uniquely represents a function whose core purpose is to process numeric values to produce a numeric result, aligning with the idea of a function that can only (or primarily) work on numeric fields. The other options either perform non-numeric-specific operations (AND), validate numeric input (ISNUMBER), or manipulate text (CONCATENATE), which do not match the notion of a function restricted to numeric data. The contrast highlights why AVERAGE is the most appropriate choice for a function centered on numeric fields.
