AIEEE 2009 ( wrong question )

The set representing the correct order of ionic radius is
A) Li⁺¹ > Be⁺² > Na⁺¹ > Mg⁺²
B) Na⁺¹ > Li⁺¹ > Mg⁺² > Be⁺²
C) Li⁺¹ > Na⁺¹ > Mg⁺² > Be⁺²
D) Mg⁺² > Be⁺² > Li⁺¹ > Na⁺¹

so Aieee 2009 got a wrong question last year
ans shuld have been
Na⁺¹ >Mg⁺² >Li⁺² > Be⁺²

wat's this. so do u thnk this too will have bunch of errors.
IIT ne to zindagi barbad kar diya ab kya AIEEE bhi waisa hi karega ?
