Which of the following represents $\mathrm{Newmann}$ eclipsed projection of ethane?

The different spatial arrangements of atoms in a molecule which are readily interconvertible by rotation about single bonds are called conformations. Conformations represent conformers which are readily interconvertible and thus non-separable. Newman projection formula for different conformations of ethane: When an ethane molecule rotates about its carbon – Carbon single bond, two extreme conformations can result in the staggered conformation and the eclipsed conformation.
