Which option is a correct example of form and balance?

Placing a heavy cube at the centre to make a stable composition

The governing concept is visual balance, in which the apparent weight, size, position, and direction of forms are arranged so that the composition feels stable or intentionally controlled. A large or heavy cube placed near the centre can distribute its visual weight around the central axis and create a stable arrangement, so option A is the best example. Placing every heavy form in one corner usually produces a strongly weighted and unstable composition unless another element deliberately counterbalances it. Accidentally cutting the main form damages emphasis and clarity. Removing a grounding shadow without purpose can make the object appear to float rather than establish balance. Balance is judged visually, not only by physical weight.
