Suppose we have a DFA $D$ with transition function $$ that operates over the alphabet $=\{0,1\}.$ What expression corresponds to final state that $D$ ends on after a computation on the string $000?$

Impossible to answer as the states for A have not been defined.

$(((q_0,0),0),0)$

$((q_0,0),0)$

$(q_0,0)$
