I was asked how to use Google Forms to allow students to choose 3 options from a list of choices. You can use Google Forms to have students rank their choices.
Grid Question
The trick to allowing students to choose a selection out of a larger list is to use the GRID style question. Select “Multiple choice grid.”

This will allow you to create a grid of rows and columns. I recommend you put your choice list in the rows. For the columns type “1st choice”, “2nd choice”, etc…

Notice in the example that I have more options in the rows than 3 choices. For this reason, make sure you do NOT have “Require a response in each row.”
3 Dots More Options Menu
While you do not want to require a response in each row, you DO want to require one for each choice (column.) Click on the 3 dots menu in the bottom right of Google Forms and select “Limit to one response per column.”
In the Spreadsheet
When you use a Multiple Choice Grid it will show the rows as their own column in Google Sheets.
