Cortical nephrons can be distinguished from juxtamedullary nephrons by
a. their location within the renal cortex. b. their filtration rate. c. the size of their renal corpuscle. d. whether they drain into a collecting duct or directly into the renal pelvis

A. their location within the renal cortex

Explanation:

Cortical nephrons are located high in the renal cortex and their loop of Henle is short. On the other hand, juxtamedullary nephrons are located near the medulla (low in the renal cortex) with long loop of Henle (deep in the medulla). Another difference between these two type of nephrons is that juxtamedullary nephrons produce more concentrated urine.
