Describe a reflection in a vertical line by drawing the line of reflection, where the line of reflection lies on the edge or outside the object ![A grid of 8 squares across and 7 squares up.  A blue isosceles triangle, labelled "P", is drawn on the grid. Its corners are at points: 4 squares up from the bottom left corner of the grid; 2 squares right and 3 squares up from the bottom left corner of the grid; 2 squares right and 5 squares up from the bottom left corner of the grid.   Another blue isosceles triangle (identical shape and size to P), labelled "Q", is also drawn on the grid. Its corners are at points: 6 squares right and 3 squares up from the bottom left corner of the grid; 6 squares right and 5 squares up from the bottom left corner of the grid; 8 squares right and 4 squares up from the bottom left corner of the grid.
A light blue vertical line, labelled "A" goes from top to bottom of the grid, 2 squares to the right of the left-hand side of the grid. A dark blue vertical line, labelled "B" goes from top to bottom of the grid, 4 squares to the right of the left-hand side of the grid. A green vertical line, labelled "C" goes from top to bottom of the grid, 5 squares to the right of the left-hand side of the grid. ]() Which is the correct line of reflection to map triangle \( \mathrm{P} \) to triangle \( \mathrm{Q} \) ? A

Believes a line of reflection must be touching the original shape
