Building breakwaters in the ocean will reduce the wave erosion.
Waves destroy cliff and coastline deposits. The silt in ocean water functions similarly to sandpaper. They degrade the beach over time. The larger the waves and the more silt they transport, the greater the erosion.
Structures built on the beach (seawalls, groynes, breakwaters/artificial headlands) or further offshore are used in hard structural/engineering alternatives (offshore breakwaters). These strategies alter coastal processes in order to slow or stop coastal erosion.
Breakwaters are offshore obstacles that protect a portion of the shoreline. They serve as a wave barrier, preventing erosion and allowing the beach to expand. Wave energy dissipation permits material transported by longshore currents to be deposited behind the breakwater. This safeguards the beach.
Therefore, the correct option is to build breakwaters in the ocean.

A thing that wouldn't be necessary condition for the growth of an empire would be internal revolutions and revolts - D.
This option, compared to the others, actually underminens the possibility of success within one empire after some time as undermining authority and creating revolutions doesn't help when creating an empire.
In an organization information flows in four directions they are downward, upward, horizontally and diagonally.
Explanation:
The communication or information flow can be between different employees and different functional parts of an organization.
Information flow control is used to track how information is passed to the program during execution and handled securely.
Downward communication is the main direction of information that involves in passing the message to one or more receivers.
I believe it is option C
Hope this helps
