The OA seems correct. Here's why:

Okay, so we have a repeating pattern of shapes that repeat every 4 times and we're told that the first shape is a triangle and the last shape is a circle. The total number of shapes have to satisfy the equation 4n+3 where n is the number of times the pattern repeats itself and the +3 at the end is where the pattern hits the circle.

E is the only choice that gives n as an integer.

4n+3=47

44=4n

n=11.

There's a +3 at the end because the circle is the third shape in the pattern and you have to add it on to the number of shapes that went by fours.
