From given condition , \left |z \right |=5

\therefore -5\leq Re\left ( z \right )\leq 5

\therefore MAXIMUM Re\left ( z \right ) can be 5 so it can't exceed 5.

\therefore Option (D)

 

Property of Modulus of z(Complex Number) -

-\left | z \right |\leq Re(z)\leq \left | z \right |

- wherein

Re(z) = Real Part of z

|z|= Modulus of z
