Focusing in ultrasound imaging is a technique used to improve image resolution by concentrating the ultrasound beam at a specific depth. One of the effects of focusing is enhancing near zone resolution by concentrating the beam, which makes option C correct. Option D is also correct as focusing results in a shorter near zone due to the concentration of the beam.

Option A, on the other hand, does not describe an effect that focusing has on the ultrasound beam. When focusing is applied correctly, it creates a smaller focal zone, not a bigger one. This is why option A is not a phrase that describes an effect of focusing on the ultrasound beam.
