To have the strip at its maximum height the figure looks like the following

The circles are connected at the centers thanks to an equilateral triangle

H is the following

so the height is \(h=2\sqrt{3}\)


Adding to this the distances on top and at the bottom of the triangle

we do have \(4+2\sqrt{3}\)

B is the answer

How can you draw the maximum width without knowing the width? The max width cannot be known and thus the maximum number of circles too can’t be known.
