Dynamic testing involves executing code while testing it to evaluate its behavior during runtime. This type of testing is essential for identifying issues that may arise during the execution of the program, such as runtime errors, memory leaks, and incorrect output based on various inputs. By running the code in a dynamic environment, testers can observe the software's actual performance and verify that it behaves as expected under specific conditions.

Static testing, on the other hand, reviews code without executing it, focusing on static analysis techniques such as code reviews and inspections. Integration testing involves combining individual software modules and testing them as a group, which can include dynamic elements but isn't solely focused on executing code. Installation testing evaluates whether software installs properly in its intended environment, again involving some dynamic testing aspects but not exclusively defined by it.

In summary, dynamic testing is pivotal for validating the functionality and performance of software by executing it and observing its behavior, making it the correct choice for the type of testing described in the question.
