sound waves travel by compression and rarefraction(pressure) of air molecules.hence nature is longitudinal and they cant be polarized and dont have components in all direction.their vibration is in the direction of disturbance causing them ,so they r called longitudinal.
so all the above are correct

Sound waves are mechanical longitudenal waves comprising of alternate compression and rarefraction so 4 is correct option.

well, sound waves are large waves, unlike mircowaves. they are larger in their width....which makes them weaker ( thus not compressed, and compression causes pressure(less energy. so id say the anwser is 3. as all wave lenths travel, if they refract, they will widen in width, unless an outside force is applied.
