The accepted answer is B. A property used to prove that certain languages are not regular by showing they cannot be 'pumped' while remaining in the language.. In computer science Pumping lemma refers to which of the following is answered by A property used to prove that certain languages are not regular by showing they cannot be 'pumped' while remaining in the language option B Option A The sequence of production rule applications used to generate a string from a grammar's start symbol does not match the stem it is a near-miss used to catch incomplete recall of A property used to prove that certain languages are not regular by showing they cannot be 'pumped' while remaining in the language Option C A finite sequence of symbols drawn from an alphabet does not match the stem it is a near-miss used to catch incomplete recall of A.
- A. The sequence of production rule applications used to generate a string from a grammar's start symbol.
Why not A: “The sequence of production rule applications used to generate a string from a grammar's start symbol.” is not correct. The accepted answer is B.
