@Arjun Sir, is the answer C?
my reasoning is as follows,
consider a grammar
S -> aA/aB
A -> cA/c
B -> bB/b
The above grammar is LL(2).
now the above grammar can be converted into LL(1) as follows
S -> aS'
S' -> cA/ϵ
S' -> bB/ϵ
similarly every other LL(2) grammar should be convertable to LL(1) grammar.
