Consider the Quicksort algorithm. Suppose there is a procedure for finding a pivot element which splits the list into two sub-lists each of which contains at least one-fifth of the elements. Let T(n) be the number of comparisons required to sort n elements. Then
A
$${\rm{T(n) < = 2T(n/5) + n}}$$
B
$$T\left( n \right){\rm{ }} < = {\rm{ }}T\left( {n/5} \right){\rm{ }} + {\rm{ }}T\left( {4n/5} \right){\rm{ }} + {\rm{ }}n$$
C
$$T\left( n \right){\rm{ }} < = {\rm{ }}2T\left( {4n/5} \right){\rm{ }} + {\rm{ }}n$$
D
$$T\left( n \right){\rm{ }} < = {\rm{ }}2T\left( {n/2} \right){\rm{ }} + {\rm{ }}n$$
