Respuesta :

Answer: Option D

Explanation: In simple words, movement along the demand curve refers to the change in the demand of a product due to change in its price. When there is a change due to factors other than price then such change brings shift in the demand curve.  

In the movement, the demand of a commodity remains constant with all other factors such as advertising, income of consumers etc.

Hence from the above we can conclude that the correct option is D.
