Correct Answer:

OCO projects power in foreign cyberspace; DCO defends DODIN

Explanation:

The key idea is the difference between offensive and defensive roles in cyberspace. Offensive Cyberspace Operations are actions intended to project power in foreign cyberspace—targeting adversaries’ networks and capabilities abroad. Defensive Cyberspace Operations aim to protect the DoD Information Network (DODIN) and other critical cyber infrastructure from attacks, keeping missions functioning. So the best statement captures that divide: offensive actions in foreign cyberspace for OCO, with DCO focused on defending DODIN. The other options blur the scope or misstate who is defended or where the actions take place.
