A Correct answer
Explanation

When defining ASCENDING or DESCENDING KEY for table sorting or searching with SEARCH ALL, the key data items must be comparable and have a total ordering. Floating-point numbers should not be used as keys because they can have representation issues (like NaN, infinity, or precision problems) that make sorting and binary search unreliable and unpredictable.
