Three plane mirrors form an equilateral triangle with each side of length

Three plane mirrors form an equilateral triangle with each side of length L. There is a small hole at a distance /> 0 from one of the corners as shown in the figure. A ray of light is passed through the hole at an angle 0 and can only come out through the same hole. The cross section of the mirror configuration and the ray of light lie on the same plane. Which of the following statement(s) is(are) correct? (A) The ray of light will come out for 0 = 30, for 0
