A Correct answer
Explanation

ASCENDING and DESCENDING keys are used for sorting and table searching operations (SORT, SEARCH ALL). Floating-point numbers are approximate values and may have tiny representation errors, making them unreliable for exact comparisons required by these operations. Therefore, floating-point items cannot be used as sort/search keys. Option A is correct.
