Correct Answer
A
Explanation
the unit of moment of a couple is newton metre The unit of moment of a couple can be expressed in newton-meters (N·m) or pound-feet (lb·ft), depending on the system of units you are using.
In the International System of Units (SI), which is the metric system, the unit for moment of a couple is the newton-meter (N·m).
In the imperial system, often used in the United States, the unit for moment of a couple is the pound-foot (lb·ft), where 1 pound-foot is the moment produced by a force of 1 pound applied at a distance of 1 foot from a reference point.
It's important to use consistent units when working with moments or torques in calculations and equations.
