\( \mathrm{S}_{1}, \mathrm{~S}_{2} \) are two coherent sources (having initial phase difference zero) of sound located along \( \mathrm{x} \) axis separated by \( 4 \lambda \) where \( \lambda \) is wavelength of sound emitted by them. Number of maxima located on the elliptical boundary around it will be :
(A) 16
(B) 12
(C) 8
