In the context of exhibiting an accepting computation path for the input aaabbb, what is the state and contents of the stack at the beginning and after each transition?
a) The initial state is S0 with an empty stack. After each transition, the stack remains empty.
b) The initial state is S0 with an empty stack. After each transition, the stack contains 'a'.
c) The initial state is S0 with 'a' on the stack. After each transition, the stack remains 'a'.
d) The initial state is S0 with 'a' on the stack. After each transition, the stack contains 'b'.
