A) 48

D) 8
E) 72
I received a PM asking me to comment.
Here's a step-by-step approach:
Number of continents that could occupy the first two positions = 3.
Number of ways to arrange the two models from this continent = 2.
Number of remaining continents that could occupy the middle two positions = 2.
Number of ways to arrange the two models from this continent = 2.
Number of remaining continents that could occupy the last two positions = 1.
Number of ways to arrange the two models from this continent = 2.
To combine the options above, we multiply:
3*2*2*2*1*2 = 48.
The correct answer is
A.
