The proximodistal principle of development refers to the pattern of development that starts from the center of the body and moves outward to the extremities. In this case, Luci is able to control her shoulder muscles (a more central part of the body) before she is able to control her hand movements (at the extremities). As she gets older, she will gain more control over her hands and be able to grasp the toy more easily. Therefore, the best answer is A) proximodistal.
