From the dynamical systems perspective,the tendency for the two arms to prefer to move in tight spatial and temporal synchrony is the result of:
A) A single generalized motor program
B) Two separate motor programs
C) An attractor
D) Motor equivalence

The tendency for the two arms to move in synchronized motion is a result of an attractor, which is a stable state of the system towards which it tends to move. In this case, the attractor is the synchronized motion of the two arms, which is preferred over any other possible motion. This is a common phenomenon in dynamical systems, where certain patterns or states emerge as stable attractors due to the underlying dynamics of the system. The other options (A, B, D) do not fully capture the nature and mechanisms of this phenomenon. A single generalized motor program or two separate motor programs would not explain why the synchronized motion is preferred over other possible motions, and motor equivalence refers to the ability to produce the same movement outcome through different motor strategies or effector systems, which is not directly relevant to the issue of synchronization.
