(D) The lowering of vapour pressure is a colligative property,which depends on the number of solute particles (van't Hoff factor,$i$) in the solution.$1.$ $NaCl 	o Na^+ + Cl^-$ $(i = 2)$$2.$ $	ext{Sucrose} 	o 	ext{Sucrose}$ $(i = 1)$$3.$ $BaCl_2 	o Ba^{2+} + 2Cl^-$ $(i = 3)$$4.$ $Na_3PO_4 	o 3Na^+ + PO_4^{3-}$ $(i = 4)$Since $Na_3PO_4$ produces the highest number of ions $(i = 4)$,it will cause the greatest lowering of vapour pressure,resulting in the lowest vapour pressure among the given solutions.
