Question

The variable isopen is to be used to indicate whether or not a store is currently open. Which of the following is the most appropriate data type for isOpen?

Answer 1

Boolean

Step-by-step explanation:

Though the options are missing, the question is still answerable.

From the question, we understand that isOpen can only assume any of two values which are: open or close

i.e. whether a store is opened or currently.

When a variable can only assume any of two values, the most suitable data type of that variable is Boolean.

Hence, Boolean answers the question.
