c. CG
  In the given problem, the place ACG and plane BCG. These planes intersect at CG in which intersection is either a point, line or curve that an entity or entities both possess or is in contact with. In the plane we can understand that the common line for both plane ACG and plane BCG is CG. Further examples can include, plane KTGX and plane KUYT, in this case you can imagine a rectangular prism in which they both intersect at line KT.

Answer:
CG

Explanation:
A plane is defined using three points.
The intersection between two planes is a line

Now, we are given the planes:
ACG and BCG

By observing the names of the two planes, we can note that the two points C and G are common.
This means that line CG is present in both planes which means that the two planes intersect forming this line.

Hope this helps :)
