Interference of Light Beams:
Interference of light beams occurs when two or more waves superpose to form a resultant wave of greater, lower, or the same amplitude. In this case, two light beams with intensities in the ratio of 9 : 4 are interfering.

Intensity of Maxima and Minima:
When two light beams interfere constructively, the intensity of the maxima is given by the sum of the intensities of the individual waves. Whereas, when they interfere destructively, the intensity of the minima is given by the difference in intensities of the individual waves.

Calculating the Intensity Ratio:
Let the intensities of the two light beams be 9x and 4x.
- Intensity of maxima = 9x + 4x = 13x
- Intensity of minima = 9x - 4x = 5x

Ratio of Intensity of Maxima and Minima:
The ratio of the intensity of maxima to minima is:
= (13x)/(5x)
= 13/5
= 25 : 1

Therefore, the correct answer is option 'D' - 25 : 1.
