$(2)\_$A table contains sales data. Each row contains data on units sold of three games $($Doom$,$ Frogger, and Tetris$)$ for a sales representative. Which of the $2$D arrays most clearly reflects this mental model of the data?

$\backslash$table$[[,$Doom,Frogger,Tetris$],[$Rep$1,150,200,100],[$Rep$2,200,400,200],[$Rep$3,250,350,150],[$Rep$4,300,380,200]]$

a$.$ int $[]$ units $=$ new int $12$

b$.$ int $[][]$ units $=$ new int $[4][3]$;

c$.{\displaystyle \underset{\phantom{}}{\overset{\phantom{}}{}}}[][]$ units $=$ new int $[3][4]$;

d$.$ int $][]$ units $=$ new int $[5][4]$;
