ACE test series

Question

I and 2 are wrong statements.

If 1 were right then since every DCFL is a recursive language the intersection of two DCFL would be DCFL which is not.

Same logic can be applied to 2.

Ace test series sucks.

Comments

If here by RL means regular language then All statement are correct, Most of test series don't have quality question thats why Gateoverflow emphasize on standard book questions

Answer is correct , all will be correct.

Ace test series sucks. They could have written regular language instead of RL. I interpreted RL as Recursive languages and hence the mistake.
