II. LALR parser is more powerful than an SLR parser: TrueCanonical LR is the most powerful parser as compared to other LR parsers. Order: LR(0)< SLR < LALR < CLR.
III. Recursive descent parsing is an example of top-down parsing: TrueRecursive descent is a top-down parsing technique that constructs the parse tree from the top and the input is read from left to right. It uses procedures for every terminal and non-terminal entity. This parsing technique recursively parses the input to make a parse tree, which may or may not require back-tracking.
Hence the correct answer is II and III.
