Answer

The pieces of the rocket fly apart willy-nilly, but the CM of these moving pieces will follow the same path that the rocket would have originally followed.

Work Step by Step

The rocket is an isolated system, and its center of mass (CM) would follow a parabolic path under the influence of Earth’s gravity (an external force). The explosion consists of forces that are internal to the system, so these cannot affect the motion of the CM.
