A
SLR(1)
B
CLR(1)
C
LALR(1)
D
Operator Precedence
Explanation: 

Detailed explanation-1: -Canonical (CLR) is the most powerful Parsers among all the LR(k) Parsers or SLR.

Detailed explanation-2: -Which of the following is the most powerful parsing method? Explanation: Canonical LR is the most powerful parser as compared to other LR parsers.

Detailed explanation-3: -CLR (1) parsing table make more number of states as compared to the SLR (1) parsing. In the CLR (1), it can locate the reduce node only in the lookahead symbols.

Detailed explanation-4: -CLR refers to canonical lookahead. CLR parsing use the canonical collection of LR (1) items to build the CLR (1) parsing table. CLR (1) parsing table produces the more number of states as compare to the SLR (1) parsing. In the CLR (1), we place the reduce node only in the lookahead symbols.

Detailed explanation-5: -The correct answer is option 3. Canonical LR is the most powerful parser as compared to other LR parsers. Order: LR(0)< SLR < LALR < CLR.
