_____ is the process of checking the dynamic type of an interface value.
- Casting
- Assertion
- Type assertion

The process of checking the dynamic type of an interface value in Go is known as "Type assertion." It is used to extract the underlying concrete value from an interface if the value is of the expected type. If the assertion succeeds, you get the value of the specified type; otherwise, it panics. Type assertion is a powerful mechanism for working with interfaces and dynamic types in Go.
