I am new to development, I have to deploy some apex classes to production and I am using change set for this. While adding components to the change set, we get an option to add dependencies. I checked dependency for one of my class and attaching this image here. My question is do I need to add all the object and fields listed here to change set. Also what if other apex class has same object or fields listed here
