What is the relationship between a text string and a substring?

A text string is the full sequence of characters you have in a cell, and a substring is a portion taken from inside that string. This lets you isolate just a part of the text—like the first few characters or a middle segment—without changing the rest. The correct idea captures that a text string is the complete group of characters, while a substring is a smaller portion derived from that string. For example, in the string “Hello world,” substrings include “Hello,” “world,” or “Hello w” (consecutive blocks from the original). The other statements misrepresent the relationship by suggesting a substring isn’t part of a string, or that strings and substrings are the same, or by describing substrings in a way that doesn’t reflect their origin from within the string.
