Answer:
Line LC
Step-by-step explanation:
Two planes always intersect in a line (unless they are parallel).
Plane GFL is the base of the prism.
Line AC is the intersection of two planes — ACG and ABLC.
Both planes intersect with the base.
The line of intersection of ACG with the base is line CG.
The line of intersection of ABLC with the base is line LC.
The only answer given in the options is
Line LC.
