The three subdivisions of electronic warfare are correctly identified as support, attack, and protection.

In the context of electronic warfare, "support" refers to the use of electromagnetic spectrum to enhance the effectiveness of friendly forces. This can include activities that facilitate communication and coordination among units, as well as preventing enemy access to the spectrum that could be detrimental to mission success.

"Attack" involves offensive actions aimed at disrupting or destroying enemy use of the electromagnetic spectrum. This includes methods like jamming enemy communications or guidance systems, effectively denying their operational capabilities.

"Protection" encompasses defensive measures that safeguard friendly forces' use of the electromagnetic spectrum. This may involve techniques to secure communications from interception or to create countermeasures against enemy electronic warfare tactics.

While the other options contain terms related to electronic warfare, they do not accurately capture the three fundamental subdivisions as established within the doctrine of electronic warfare.
