Which of these represents the set of complex numbers zzz such that Re(z2)>0\text{Re}(z^2) > 0Re(z2)>0?
∣arg(z)∣<π4|\arg(z)| < \frac{\pi}{4}∣arg(z)∣<4π or ∣arg(z)∣>3π4|\arg(z)| > \frac{3\pi}{4}∣arg(z)∣>43π
∣arg(z)∣<π2|\arg(z)| < \frac{\pi}{2}∣arg(z)∣<2π
∣arg(z)∣>π2|\arg(z)| > \frac{\pi}{2}∣arg(z)∣>2π
−π4<arg(z)<π4-\frac{\pi}{4} < \arg(z) < \frac{\pi}{4}−4π<arg(z)<4π
