AI explanation

To answer this question, we need to understand what single-row functions are and how they operate.

Single-row functions are functions in SQL that operate on a single row and return a single result per row. These functions take one or more arguments and perform calculations or manipulations on the values of the row to produce a single output value.

Since single-row functions are designed to operate on a single row and return a single result, they cannot return multiple results per row. Therefore, the correct answer is:

B) False - Single-row functions cannot return multiple results per row.
