Best way to add a 900 option dropdown list on registration form

Hello support,

Could you please advice the best way for adding a dropdown selection list with approx. 900 options on the registration form of EasySocial? Instead of adding these 1 by 1 manually I would like to import them directly into the database by using phpmyadmin. Could you provide me with a query to run, so I can import a csv file containing the 900 options?
The csv datafile will be like this

option1,;placeoption1
option2;placeoption2
option3;placeoption3
...and so on...

Thanks and regards
