Statement I: TRUE.
L = {an |n ≥ 0} ∪ {anbn| n ≥ 0}
{an |n ≥ 0} is a regular language and {anbn| n ≥ 0} is a DCFL and hence, there Union would be a DCFL.
L = {an |n ≥ 0} ∪ {anbn| n ≥ 0}
{an |n ≥ 0} is a regular language and {anbn| n ≥ 0} is a DCFL and hence, there Union would be a DCFL.
Statement II: FALSE.
L is DCFL then it is CFL too.
L is DCFL then it is CFL too.
Statement III: TRUE
L cannot be LL(k) for any number of look-ahead. LL(k) cannot conclusively distinguish that whether the string to be parsed is from an or from anbn. Both have a common prefix.
