Given $2$ algorithms, A and B$,$ and their respective orders of growth.

$C(n{)}_A$inO$(n^3)$

$C(n{)}_B$inO$(nlogn)$

Also, given an algorithm $D$ which consists of executing algorithm A first, then executing algorithm B$.$

What is the order of growth of algorithm D$?$

$C(n{)}_D$inO$(n^{3}logn)$

$C(n{)}_D$inO$(nlogn)$

$C(n{)}_D$inO$(n^3)$

$C(n{)}_D$inO$(logn)$
