The dry saturated steam at very low pressure, (510 kg/cm²) when throttled to atmosphere will become

thanks for your explaination Kanchan Abhishek

First of all the answer giving for the question 5-10 kg/cm^2 pressure that's why I m giving to explanation for 5-10 kg/cm^2 pressure.we can clearly visualize from TS diagram of water that at lower pressure when throttling occurs of dry saturated steam will reach at superheated region but for higher pressure(150 kg/cm2) dry saturated steam will reach in wet region.
