When in a Newman projection the major groups or atom are remain in opposite direction (theoretical angle between them is 180 degree),then this conformation is called anti conformation.
In butadiene the mejor group is methyl group. So,in which conformation the methyl group remain opposite ,this conformation will be anti conformation.
In the picture in option D the the two methyl groups are opposite in direction.
So the answer is d
