Grammar and style checkers:

A) effectively point out any computing error in excel sheets.
B) help users understand the rudimentary basics of grammar.
C) does not help identify possible slangs.
D) does not help identify possible misused words.
E) help identify possible problems and give suggestions for revision.

Grammar and style checkers help identify possible problems and give suggestions for revision. Option A is specific to Excel sheets and not related to grammar or style. Option B is too general and vague, and grammar checkers do not necessarily cover rudimentary basics, but instead, they focus on specific grammar rules. Option C is incorrect, as grammar and style checkers can identify slang words or phrases. And option D is incorrect because identifying misused words is one of the primary functions of grammar and style checkers.
