This is a unit cell
True
To get the answer of this question, we have to know the difference between the unit cell and a lattice.
Lattice is the periodic arrangement of the points such that the environment at any point is the same as that at any other point. Every point in lattice should have same surroundings.
We can express unit cell in terms of lattice points.
The simplest repeating unit in a crystal is called a unit cell. Each unit cell is defined in terms of lattice points. The points in space about which the particles are free to vibrate in a crystal.
Therefore it is a unit cell.
