Which licenses we can use in a theme development



I am stucking in which plugins to use in a theme,

GPL - L2

Please explain me in simple words, which of them, I can use in a theme to sell it on Envato. I don’t need links of the licenses description.

Also tell me if other type of license is there

Also, Can I use TGM Plugin Activation class for wordpress. It is released under GPL - L2


Yep any of those. Yes please use tgmp
