B (watts)
Explanation
## Step 1Power is defined as the rate at which work is done or energy is transferred. In the International System of Units (SI), the unit of power is the watt (W), which is equivalent to one joule per second (1 J/s).## Step 2The other units presented in the options, namely joules (J), meters per second (m/s), and newtons per meter (N/m), are not units of power.## Step 3Joules are a measure of energy, work, or amount of heat. ## Step 4Meters per second is a measure of speed or velocity.## Step 5Newtons per meter can refer to a unit of tensile strength or elasticity, not power.
