Consider three hypothetical ionic compounds `AB, A_(2)B` and `A_(2)B_(3)`, where in all the compounds B is in `-2` oxidation state and A has a variable oxidation state. What is the correct order of lattice energy for these compounds ?

A

`A_(2)B gt AB gt A_(2)B_(3)`

B

`A_(2)B_(3) gt AB gt A_(2)B`

C

`AB gt A_(2)B gt A_(2)B_(3)`

D

`A_(2)B_(3) gt A_(2)B gt AB`
