Explanation

LENGTH is the correct function in SAP Build Apps for returning the number of items in a list (array). It operates on list/array data types and returns an integer count of how many elements the list contains.

• COUNT (A) is a distractor borrowed from SQL/database contexts where it counts rows - SAP Build Apps uses formula-based logic, not SQL, so COUNT is not the function here.
• MAX (C) returns the largest numeric value within a list, not the number of items in it.
• SUM (D) adds up numeric values in a list, again operating on the content of items rather than the quantity of them.

Memory tip: Think of LENGTH like measuring the length of a physical list of items - just as you'd count how long a piece of paper is, LENGTH tells you how many entries your list holds. If you've used JavaScript or Python, this maps directly to .length (JS) or len() (Python).
