Given DFA "A" is not minimal, if we apply minimization on it we will end up with 2 states. One state will be formed by two non final states, Second state will be single final state.So Minimal DFA will be of 3 states.
DFA "A" is also accepting string of length one, for eg:{ 0 } is also accepted.
By looking at these two conditions, point number 3 and 4 will be false.
option (D) will be answer......
