A

Step 1: Understand the relationship between power (P), torque (τ), and angular velocity (ω). The formula connecting these quantities is given by:
$$ P = τ imes ω $$
where P is the power in watts, τ is the torque in newton-meters (N·m), and ω is the angular velocity in radians per second (rad/s).

Step 2: Convert angular velocity from RPM to rad/s.
The conversion is done using the relation:
$$ ω = rac{2 ext{π} imes ext{RPM}}{60} $$
Substituting the given RPM value:
$$ ω = rac{2 ext{π} imes 2100}{60} = 220 ext{ rad/s} $$

Step 3: Rearrange the power formula to solve for torque (τ):
$$ τ = rac{P}{ω} $$

Step 4: Substitute the values of power and angular velocity into the torque formula:
$$ τ = rac{220 ext{ W}}{220 ext{ rad/s}} = 1 ext{ N·m} $$

Step 5: Therefore, the torque produced by the motor is:
$$ τ = 1 ext{ N·m} $$
Hence, the answer is option A.
