Which one of the following is CORRECT?
(A) Only (I)
(B) Only (II)
(C) Both (I) and (II)
(D) Neither (I) nor (II)
Answer: (A)
Explanation: L1.L2 is definitely regular, since regular languages are closed under concatenation.
But L1.L2 = { anbn | n ≥ 0 } is not correct. Because both variable are independent of each other.
L1.L2 = { anbm | n ≥ 0 , m ≥ 0 } is possible.
Therefore, only statement (i) is TRUE.
