Why the Other Options Are Wrong
Option A: 106.7 cy
106.7 cy is below the supported result for excavation takeoff; it likely uses the wrong base, period, or account bucket.
Option B: 128.0 cy
128.0 cy is below the supported result for excavation takeoff; it likely uses the wrong base, period, or account bucket.
Option C: 170.7 cy
170.7 cy is above the supported result for excavation takeoff; it likely adds an unsupported amount or compares the wrong financial base.
