About this MCQ
This Hard Theory of Computation (Automata) MCQ checks one syllabus fact.
The question is: “Choose the correct description of Derivation.”
The accepted answer is B. The sequence of production rule applications used to generate a string from a grammar's start symbol.. Choose the correct description of Derivation is answered by The sequence of production rule applications used to generate a string from a grammar's start symbol option B Option A 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 The sequence of production rule applications used to generate a string from a grammar's start symbol Option C A class of languages for which a Turing machine will accept and halt on strings in the language but may not halt on strings outside it does not match the stem it is a near-miss used to catch incomplete recall of The sequence of production rule applications used to.
- A. A finite sequence of symbols drawn from an alphabet.
