Let $\mathbb{C}$ denote the set of all complex numbers. Define
$$\begin{aligned}
& A = \{ ( z , w ) \mid z , w \in \mathbb{C} \text{ and } | z | = | w | \} \\
& B = \left\{ ( z , w ) \mid z , w \in \mathbb{C} , \text{ and } z ^ { 2 } = w ^ { 2 } \right\}
\end{aligned}$$
Then,\\
(A) $A = B$\\
(B) $A \subset B$ and $A \neq B$\\
(C) $B \subset A$ and $B \neq A$\\
(D) none of the above
