Correct answer: c) Whether a vessel can navigate through pack ice depends solely on how closely packed the floes are.

Navigability through pack ice depends not only on floe concentration, but also on the thickness, size and hardness of the floes and the vessel’s strength and power.
Why the others are not
a) True: growlers drift to leeward of the iceberg.
b) True: shallow, less saline coastal waters freeze first.

How to work it out in the exam
False: that pack-ice navigation depends only on concentration (also thickness and size).
