Correct answer: A
A predictive parser is a kind of LL(1) parser , which follows a top-down parsing approach that builds the parse tree from the start symbol using lookahead. It does not use bottom-up or shift–reduce parsing techniques, so only the top-down approach is correct for predictive parsers.
