Final answer:

The statement 'The cortex covers the capsule' is false about the kidney's anatomy; it's actually the capsule that covers the cortex. The renal pelvis collects urine, the cortex contains nephrons, and the renal columns are extensions of the renal cortex separating the pyramids.

Step-by-step explanation:

The question involves understanding the structure of the kidney. The renal pelvis is a funnel-shaped space in the innermost part of the kidney that collects urine before it moves into the ureter. When considering the statements provided, the false statement is c) The cortex covers the capsule. In fact, it is the renal capsule that covers the cortex, not the other way around. The renal cortex is the outer layer of the kidney where the nephrons, the functional units of the kidney, are located. The renal medulla is situated inside the renal cortex and contains the renal pyramids and papillae. The hilum is a recessed area through which the renal artery, vein, ureters, and nerves enter and exit the kidney. Finally, the renal columns are the extensions of the renal cortex that project into the medulla and separate the renal pyramids.
