Four open-topped microfluidic tracks (1, 2, 3, and 4) contain static liquids of various densities. Track 1 contains a liquid of density \(\rho_0\) in a slanted zig-zag channel, with Node 1 located at a vertical depth of \(2h_0\) below the surface (and a channel distance of \(4h_0\)). Track 2 contains a liquid of density \(3\rho_0\) in a wide funnel-shaped channel, with Node 2 located at a vertical depth of \(h_0\). Track 3 contains a liquid of density \(\rho_0\) in a multi-bulbed channel, with Node 3 located at a vertical depth of \(3h_0\). Track 4 contains a liquid of density \(0.5\rho_0\) in a uniform vertical channel, with Node 4 located at a vertical depth of \(4h_0\). Which of the following correctly ranks the total hydrostatic pressure \(P\) at the four marked nodes?
