Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A): In ultrasonography, the axial resolution and the maximum available depth of examination is higher for higher frequency transducers.
Reason (R): The high frequency transducers produce shorter pulses with longer pulse interval, and are attenuated early in the tissues due to higher number of interactions.
In light of the above statements, choose the most appropriate answer from the options given below.
