(D) The formula for the number of images $(n)$ formed by two plane mirrors inclined at an angle $(	heta)$ is given by $n = (360^{\circ} / 	heta) - 1$.Given the angle $	heta = 72^{\circ}$.First, calculate the value of $360^{\circ} / 	heta = 360^{\circ} / 72^{\circ} = 5$.Since the result is an odd integer, the number of images formed is $n = 5 - 1 = 4$.This formula applies regardless of whether the object is placed symmetrically or asymmetrically when the result of $360^{\circ} / 	heta$ is an odd integer.

If an object is placed symmetrically between two plane mirrors, inclined at an angle of $72^{\circ},$ then the total number of images formed is
