A variable being dynamically typed means that its type is not fixed at the time of definition but can change during the program's execution. This characteristic allows for greater flexibility in how variables can be used, as the same variable can store values of different types at different times. For instance, a variable might first hold an integer value and later be assigned a string value without any errors or additional type declarations needed. This is particularly useful in languages that support dynamic typing, as it allows for more concise and adaptable code.

In contrast, a fixed type means that once a variable is defined as a certain type, it cannot change to another type throughout its lifespan in the program. The incorrect choices highlight different aspects of variable typing, such as strictness or limitations in what types of data can be held, but they do not capture the essence of dynamic typing, which emphasizes the ability to change the type of the variable during execution.
