In free space, the condition that holds good is(a) Minimum attenuation

1.	In free space, the condition that holds good is(a) Minimum attenuation and propagation(b) Minimum attenuation and maximum propagation(c) Maximum attenuation and minimum propagation(d) Maximum attenuation and propagationThis question was addressed to me in examination.Question is taken from Plane Waves in Free Space topic in portion EM Wave Propagation of Electromagnetic Theory
Answer» Right option is (b) Minimum ATTENUATION and maximum propagation Best EXPLANATION: The free SPACE does not have any BARRIER for attenuation. Thus it enables minimum attenuation and maximum propagation. This technique is employed in line of sight COMMUNICATION.
