Answer:
C. "text string"
Step-by-step explanation:
In programming, when you want to include a text string (a sequence of characters) in your code, you enclose the text within double quotation marks ("). This is known as a string literal.
I put an example in the picture below!
The double quotation marks indicate to the compiler that the characters between them should be treated as a string of text. Using single quotation marks (' ') or forward slashes ('//') as shown in the options wouldn't serve the purpose of defining a text string in programming languages like C++, Java, or Python.
