The question is: “In computer science, Lexeme refers to which of the following?”

The accepted answer is C. A sequence of characters in source code that matches the pattern for a token.. In computer science Lexeme refers to which of the following is answered by A sequence of characters in source code that matches the pattern for a token option C Option A The compiler phase that improves intermediate or final code to make it run faster or use fewer resources does not match the stem it is a near-miss used to catch incomplete recall of A sequence of characters in source code that matches the pattern for a token Option B A program that translates an entire source program written in a high-level language into machine code before execution does not match the stem it is a near-miss used to catch incomplete recall of A sequence of characters in source code.
