What pines in Arduino UNO are GPIO and what pines are I2C

Hello,

As the title say, I want to know what pines are GPIO and what pines are I2C. And I want to know if in any of them the pin needs to be analog or digital. Thanks for your help.

They can all be used for GPIO. Pins A4 and A5 are the I2C pins. But even they can be used as GPIO when not being used for I2C.
