Multiple and Single Choice Question gives you the ability to list multiple possible options to a question.
The main difference between Multiple and Single Choice is:
Multiple Choice allows you to select more than one option to the question
Single Choice allows you to only select one option to the question.
Below is examples from published questions to show how they look.
As you can see the question is posed in a way to ask the user to choose possibly more than one option.
The user has the ability to choose 1, 2, 3 or all of the options.
In a single choice we only give the user the ability to choose only one option.
If the user changed their option from Black to Red, then only Red will be displayed.
