Which mechanism diminishes VHF radio signal propagation under stratified atmospheric conditions?

A)Ducting creates guided wave paths
B)Refraction bends waves earthward more
C)Scattering increases signal path loss
D)Diffraction overcomes terrain obstructions

💡 Explanation

Signal scattering reduces VHF radio signal strength because atmospheric irregularities cause energy dispersion via incoherent reflections of radio energy rather than concentrated directional propogation; therefore path loss increases as signal energy is bounced around rather than travelling directly.
