I think its B. Please keep in mind that I could be wrong.
Explanation:
An absorption spectrum occurs when light passes through a cold, dilute gas and atoms in the gas absorb at characteristic frequencies; since the re-emitted light is unlikely to be emitted in the same direction as the absorbed photon, this gives rise to dark lines (absence of light) in the spectrum.

The correct answer to the question is 2.27
i.e the acceleration of the body is 2.27
along the forward direction.
CALCULATION:
As per the question, the net external force on the propeller of model airplane F = 6.8 N.
The mass of the model air plane m = 3.0 kg
We are asked to calculate the acceleration of the air plane.
From Newton's second law of motion, we know that the net external force acting on a body is equal to the product of mass with acceleration of that body.
Mathematically force F = m × a
⇒ 

[ans]
The direction of acceleration is along the direction of force. Hence, the acceleration of the propeller is 2.27
along forward direction.
