Answer 2

Linus Torvalds wrote Linux in the early to mid-1990s based off of Berkley's BSD project. Because BSD required liscensing (16 max) Linus wanted to create a similar platform but free, so he created Linux. Most assuredly Linux is mostly written in C with patches and wrappers built in to handle other language additions. This link has an interview with Linus about why and how he created Linux: https://arstechnica.com/information-technology/2015/08/how-linux-was-born-as-told-by-linus-torvalds-himself/
