Which of the following is a vector quantity that acts in the same direction as the net force applied on a body?
Acceleration
By Newton's second law, \(\vec{F} = m\vec{a}\), so the acceleration produced in a body is always directed along the same line as the net applied force, since mass is a positive scalar.
Work and distance are scalar quantities with no direction, and speed is also a scalar, being just the magnitude of velocity.
Acceleration, however, is a vector quantity, and it necessarily points in the same direction as the net force causing it.
Hence, the correct answer is acceleration.
