Solution

The correct option is D remain in the same position relative to the water.
According to the Archimedes' principle, an object placed on water displaces the volume of water which weighs equal to the weight of the submerged part of the object. When beaker starts accelerating, the apparent weights of the displaced water and the wood are still equal, and so the wooden piece reamins at the same level relative to water.
