Suppose

a \in \mathbf{R}

and the equation

z+a|z|+

2 i=0

has no solution in

\mathbf{C}

, then

a

satisfies the relation.

View answer and explanation

Correct option: B

|a| \geq 1

Option B (

|a| \geq 1

) is correct because the equation has no solution when the coefficient of |z|^2 is non-positive, which occurs when

|a| \geq 1
