The height of mercury barometer is \( h \) when the atmospheric pressure is \( 10^{5} \mathrm{~Pa} \). The pressure at \( x \) in the shown diagram is
(a) \( 10^{5} \mathrm{~Pa} \)
(b) \( 0.8 \times 10^{5} \mathrm{~Pa} \)
(c) \( 0.2 \times 10^{5} \mathrm{~Pa} \)
(d) \( 120 \times 10^{5} \mathrm{~Pa} \)
