Answer:
A. Aluminium
Explanation:
Buoyant force is simple terms refers to the weight of water displaced when an object is immersed in it. The higher the volume of an object, the higher the buoyant force.
From the problem, we have two metals of equal mass, aluminium and lead, of which lead is denser.
density =
Volume =
This means that the volume of each metal depends on the density, and for the fact that lead is denser , it will have a lower volume than aluminium which means Aluminium will have a greater buoyant force.
