Answer:
Symmetrical balance.
Explanation: Anatomically, equal distribution of body organs and parts within an organisms to give proportions of shapes, sizes, and forms of the divided sides or halves is called body symmetry
Asymmetrical balance has two sides with each side's size, shape and placement form different from one another, (not match) but yet well balanced.
Therefore the correct option is Symmetrical balance, just like mirror image in which the two side are exactly matched and balanced.
Therefore, if an imaginary line is vertically drawn through the center of composition of the object then the forms on each side of the axis produced should be proportionate to one another in size, shape and placement.They may be view as mirror image of one another but not with 100% perfect similarity.
In ideal cases to get a perfect symmetrically balanced composition, centering is the method usually used.However, most center design may produce flat shape which may be not give good symmetry.
