Which of the following is $NOT$ a part of the renal pyramid?

Which of the following statements is correct?

Match the following columns:

Column-$I$	Column-$II$
$P$. Structures in renal cortex	$I$. Descending limb of Henle
$Q$. Structures in renal medulla	$II$. Proximal convoluted tubule $(PCT)$
	$III$. Distal convoluted tubule $(DCT)$
	$IV$. Ascending limb of Henle
	$V$. Collecting duct
	$VI$. Duct of Bellini
	$VII$. Afferent arteriole

The main function of the renal pyramids of the kidney is to:

Given below are two statements: one is labelled as Assertion $A$ and the other is labelled as Reason $R$.
Assertion $A$: Nephrons are of two types: Cortical and Juxta-medullary,based on their relative position in the cortex and medulla.
Reason $R$: Juxta-medullary nephrons have a short loop of Henle,whereas cortical nephrons have a longer loop of Henle.
In the light of the above statements,choose the correct answer from the options given below:
