Answer: A
Visibility is the greatest distance an observer can see.
Meteorological visibility is defined as the greatest distance at which a suitable dark object can be seen and identified against the sky at the horizon by day, or a light of moderate intensity seen at night. It is reduced by fog, haze, dust and precipitation.
The other options turn the definition upside down: a shortest distance makes no sense as a limit of sight, and a distance one 'cannot see' is not what an observer reports.
