A
Correct answer
Explanation
In PL/SQL (specifically in SQL*Plus environment), the '&' symbol is indeed used to create substitution variables for user input. When you place '&' before a variable name in a SQL statement, SQL*Plus prompts the user to enter a value for that variable. This is commonly used for creating interactive scripts and for dynamic value substitution during runtime.
