In Finite Element Method (FEM), for discretization purpose in general, which optionis not true for mesh refinement?

Previous meshes should be contained in the refined mesh

Any point in the body can be included within an arbitrarily small element at any stage of the mesh refinement

The same order of approximation for the solution may be preserved through all stages of the refinement process

Elements with very large aspect ratios are desired
