What is the correct order for increasing lattice enthalpy?

A.     ${\text{MgO}} < {\text{MgC}}{{\text{l}}_{\text{2}}} < {\text{NaCl}} < {\text{CsCl}}$

B.     ${\text{CsCl}} < {\text{NaCl}} < {\text{MgC}}{{\text{l}}_{\text{2}}} < {\text{MgO}}$

C.     ${\text{NaCl}} < {\text{CsCl}} < {\text{MgO}} < {\text{MgC}}{{\text{l}}_{\text{2}}}$

D.     ${\text{NaCl}} < {\text{CsCl}} < {\text{MgC}}{{\text{l}}_{\text{2}}} < {\text{MgO}}$
