A. Telephone Number
B. Units on Hand
C. First Name
D. Gender
E. City

Answer 1

A Telephone Number is commonly defined with an input mask to ensure data is entered in a standardized format, such as (999) 999-9999.

Step-by-step explanation:

An input mask is a tool used in data entry to help ensure data is entered into a database correctly. It defines the format in which data should be entered, guiding the user with placeholders and specific format requirements. Among the given options, a Telephone Number is commonly defined with an input mask because it follows a standardized format which may include elements like parentheses, dashes, and spaces. For example, an input mask for a U.S. telephone number might look like (999) 999-9999, where the number 9 represents a placeholder for a digit. Input masks are less suitable for data types that do not have a standard format, such as first names or cities.
