Dynamic typing refers to a programming paradigm in which the type of a variable is determined at runtime rather than at compile time. This means that you can assign values of different types to the same variable during the execution of the program. For example, a variable might initially hold a string value and later can be re-assigned to hold an integer value without any compilation errors. This flexibility allows for more dynamic and fluid coding practices, as programmers do not need to rigorously specify types ahead of time.

In contrast, systems that rely on static typing, where types are checked and assigned at compile time, do not allow such flexibility, making it necessary to define the types of variables explicitly before using them. The other options describe concepts that do not align with the definition of dynamic typing, such as static analysis methods or compile-time type determination, which do not involve changing variable types during execution.
