Ktorá z nasledujúcich možností vysvetľuje stratégiu geografických experimentov Zvýšenie?

The correct answer describes a "Lift" geographic experiment strategy. In this type of experiment, the goal is to measure the incremental impact of an increased budget or specific campaign changes. Therefore, the experimental group receives an increased budget to test the effect of that lift, while the control group's budget remains unchanged to serve as a baseline for comparison. This allows for the isolation and measurement of the additional performance generated by the increased investment. The incorrect options describe scenarios that would either reduce spending in the experimental group, which is not a "lift" strategy, or manipulate the control group's budget in a way that wouldn't accurately measure the impact of an increased budget on the experimental group.
