\left|z_{1}+z_{2}\right|^{2}+\left|z_{1}-z_{2}\right|^{2}

is equal to

View answer and explanation

Correct option: B

2\left(\left|z_{1}\right|^{2}+\left|z_{2}\right|^{2}\right)

Option B is correct because |z1+z2|^2 + |z1-z2|^2 simplifies to 2(|z1|^2 + |z2|^2) using the properties of complex numbers.
