In the given question we are asked to pick what described line GI.
Step-by-step explanation
In the question, we are given four possible options which are
1) Perpendicular bisector of FH
2) Angle bisector of G
3) Median of triangle FGH
4) Altitude of triangle FGH
Considering options 1. 2, 3, we should note that the trio of options will require a confirmation that angle G is truly bisected by GI. Since there is no indication of that on the image, it implies that the only accurate option is
Answer: Altitude of triangle FGH
