Connection of a phase rotation meter allows a circuit to stay _____ with leads clamped onto the test points.

Explanation:
A phase rotation meter is used to determine the order of the three phases without breaking the circuit. When you clamp the leads onto the test points, the measurement path is added without disconnecting any conductors, so current can continue to flow through the load. That keeps the circuit in a closed, or complete, state. Opening the circuit would interrupt current and disrupt operation, while energizing or safety concerns aren’t what this wording targets—the key idea is maintaining continuity while taking the reading.
