Answer 2

${\huge {\mathfrak {Answer :-}}}$

◾This is possible when B = 0.

◾Let's take the value B = 0,

So, |A + B| = |A - B|

Or, |A + 0| = |A - 0|

Or, |A| = |A|

Or, A = A. ✔️

◾Also possible for A = 0.

◾Let's take the value,

So, |A + B| = |A - B|

Or, |0 + B| = |0 - B|

Or, |B| = | - B|

Or, B = B. ✔️

⚫ Hence, verified.

Done..
