The proximity of pack ice may be indicated by _______________.

A icebergs
B changes in seawater salinity
C glare on clouds on the horizon
D changes in air temperature
AI Explanation

The correct answer is C) glare on clouds on the horizon. The presence of pack ice can be indicated by a glare or bright reflection on the clouds near the horizon. This is caused by the sunlight reflecting off the flat, smooth surface of the pack ice. The other options are not reliable indicators of nearby pack ice - icebergs may be distant from the pack, salinity and air temperature changes can have other causes, but the distinctive cloud glare is a clear sign of the proximity of pack ice.
