How to show data stored (sql server database) in a 'select option' with json or/and javascript?

I'm new in the mvc world, so, I don't understand a couple of things. I'm working with c#, javascript and sql server to do a webservice. The point is that I need to show data from a table by populating a 'select option' (created with javascript) and I would like to do this with javascript, json or jquery, without php. Please, I need you to be specific for me to understand. Thank you for your attention and help!
