Consider the regular octagon below with a center at the organ and a vertex at 4,0

B. Reflection across line y = 0

Step-by-step explanation:

Reflection across line y = 0 is equivalent to reflection over x-axis, which transforms point (x, y) into (x, -y).

The coordinates of the octagon are:

(-4, 0)

(-2.9,  2.9)

(0, 4)

(2.9,  2.9)

(4, 0)

(2.9,  -2.9)

(0, -4)

(-2.9,  -2.9)

which are transformed into:

(-4, 0) -> (-4, 0)

(-2.9,  2.9) -> (-2.9,  -2.9)

(0, 4) -> (0, -4)

(2.9,  2.9) -> (2.9,  -2.9)

(4, 0) -> (4, 0)

(2.9,  -2.9) -> (2.9,  2.9)

(0, -4) -> (0, 4)

(-2.9,  -2.9) -> (-2.9,  2.9)

which coincided with the original octagon
