B Correct answer
Explanation

The ASCII() function typically returns the ASCII value of the FIRST character of a string, not the entire string. It's a single-character function - passing a multi-character string only processes the first character. The question is misleading about displaying 'ASCII code of the string'.

AI explanation

The ASCII() function (as found in SQL dialects like MySQL/SQL Server) returns the ASCII code of only the first character of a string expression, not a representation of the whole string's characters. So the statement's implication — that ascii() displays 'the corresponding ASCII code of the string' as if applying to the entire enclosed string — is inaccurate; it only evaluates the leading character. Because the statement overstates what the function does, False is the correct answer, reflecting that ascii() is a single-character, not whole-string, operation.
