Explanation:

Gating Ratio:
The gating ratio in a gating system refers to the proportion of different components in the system.

Components:
- Sprue: The main channel through which the molten metal flows from the ladle to the runners.
- Runner: Channels that distribute the molten metal from the sprue to the ingates.
- Ingate: The entry point through which the molten metal enters the mold cavity.

Ratio:
The gating ratio 2 : 8 : 1 for copper in a gating system refers to the ratio of areas of the different components.
- Sprue : Runner : Ingate
- The ratio indicates that for every 2 units of area in the sprue, there are 8 units of area in the runner, and 1 unit of area in the ingate.
- This ratio is important for ensuring proper flow of molten metal and avoiding defects in the casting process.
Therefore, the correct answer is option A, which represents the ratio of areas of sprue, runner, and ingate in the gating system.
