The character sequence used to denote a newline in output is represented by '\n'. This sequence is part of the standard escape sequences in many programming languages, including Python, C, Java, and others. When included in a string, it tells the interpreter or the compiler to move the cursor to the next line when outputting that string to a display or a file.

This is crucial in formatting output for readability; for instance, without the newline character, all output would appear on the same line, making it hard to read or follow.

The other choices represent different types of escape sequences or control characters. For instance, '\t' is used for inserting a tab space, '\\n' is not a standard escape for a newline (the backslash itself would not be interpreted as a newline character when another backslash follows), and '\r' represents a carriage return, which moves the cursor to the beginning of the line but does not advance it to the next line. Understanding these nuances helps in correctly formatting and manipulating output in programming.
