Correct answer: 50% of pixels in view for at least 1 second.
Why this is the answer
The correct answer is 50% of pixels in view for at least 1 second. This is the industry-standard viewability definition set by the Media Rating Council (MRC) for display ads, which Amazon DSP adheres to. For a display ad impression to be counted as "viewable," at least 50% of its pixels must be visible on an active browser tab for a minimum of one continuous second. Other options like 10% or 100% of pixels, or longer durations like 2 or 3 seconds, do not align with the established MRC standard for display ad viewability.
