In general, a reinforced vessel can safely navigate in ice provided the concentration does not exceed how many tenths?

A 1-2 tenths
B 3-4 tenths
C 5- 7 tenths
D 8- 9 tenths with icebreaker assistance
AI Explanation

The correct answer is C) 5-7 tenths. A reinforced vessel can safely navigate in ice provided the ice concentration does not exceed 5-7 tenths. This is because at ice concentrations above 5-7 tenths, the ice becomes too dense and compact for a reinforced vessel to safely navigate without the assistance of an icebreaker. Options A and B are too low, while option D requires icebreaker assistance, which is not the case for a reinforced vessel navigating in 5-7 tenths of ice concentration.
