Consider the grammar given by the following productions:

E -> E + E| T | b

T -> T * T | a

Which of the following are the First and the Follow Sets for variables E and T?

1- First(E) = {a,b}; Follow(E) = {+}; First(T) = {a}; Follow(T) = {*}

2- First(E) = {a,b}; Follow(E) = {+,*}; First(T) = {a}; Follow(T) = {+, *}

3- First(E) = {a,b}; Follow(E) = {+}; First(T) = {a}; Follow(T) = {+, *}

4- First(E) = {a}; Follow(E) = {+}; First(T) = {a}; Follow(T) = {+, *}
