Conformations are different arragements ...

Conformations are different arragements of atoms htat are interconverted by rotation about single bond.
IN eclipsed conformation, the `C-H` bond on one carbon is directly aligned with `C-H` bond on the adjacent carbon.
In staggered conformation, the `C-H` bond on one carbon bisect the `H-C-H` bond angle on adjacent carbon.
The angle that seperates a bond on one atom form a bond on a adjacent atom is called a dihedral angle.
A staggered conformation with two larger groups `180^(@)` from each other is called anti. A staggered conformation with two larger group `60^(@)` from each other is called gauche
Which of the following conformer of butane has minimum energy?
