Correct Answer: B. (a), (b), (c), (d), (e)
Solution:The correct sequence in a top-down syntactic analysis by computers is as follows:
(a) Load grammar-lexicon: The grammar and lexicon needed for syntactic parsing are loaded.
(b) Read input sentence: The system reads the sentence to be analyzed.
(c) Search for S node in the grammar and proceed downwards: The parser looks for the S (Sentence) node, starting the syntactic structure from the toр.
(d) Search POS categories in Lexicon: Part-of-speech categories are identified in the lexicon to parse the words.
(e) Display results: The final parsed structure or result is displayed. This order is typically followed in top-down parsing methods in computational linguistics.
