I do not know why there is so much confusion regarding this question
People who are saying only $GOTO$ is mentioned not the action part, think of one thing, what do we call GOTO?
From a state if we go to the next state using a NON-Terminal production then that is GOTO
But here in the question it is clearly mentioned that we need to find
The number of items in the set $GOTO(I_0,⟨)$
here $⟨$ is a terminal symbol right? So why so much fuss about non terminal GOTO part
They meant to ask the number of items in the canonical collection set of $GOTO(I_0,⟨)$
