The function that allows for reading an entire line of text into a string object, including embedded spaces, is indeed `getline()`. This function is designed to read input from a stream, typically `std::cin`, until a newline character is encountered. The entire line, including any spaces, is stored as a complete string in the provided string variable. This is particularly useful when dealing with user input where spaces may be significant, such as in a full name or a sentence.

On the other hand, the `get()` function, while also capable of reading input, only takes one character at a time or reads up to a specified number of characters, which does not support reading an entire line with spaces intact.

`cin()` is not a valid C++ function for reading input; rather, `cin` is an object used to represent the standard input stream.

The term `readline()` is not part of standard C++ and may be found in other programming languages or libraries, but it does not exist in the context of C++’s standard input/output features.

Thus, `getline()` is the correct answer as it effectively captures an entire line of input, including spaces, into a string object.
