Which condition has all valves and fittings in system X and Y closed?

• A. Condition Zebra
• B. Condition Alpha
• C. Condition Yoke
• D. Condition X-ray

Answer: (C)

In damage control, readiness conditions define exactly which valves and fittings are open or closed to control flooding and isolate parts of the ship. Condition Yoke specifies that all valves and fittings in system X and system Y are closed, so those two lines are completely sealed off. That precise isolation is why it’s the best choice for a scenario asking to have every valve and fitting in both systems closed. The other conditions describe different valve configurations for other situations, so they don’t achieve the full X and Y isolation that Yoke provides.
