Why in the following code example presented in the slides:

int

$*$

arr

$[$

$]$

$=$

$\{$

$$malloc

$($

$1$

$2$

$)$

$,$

$$malloc

$($

$2$

$0$

$)$

$,$

$$malloc

$($

$4$

$)$

$\}$

;

all the rows allocated with malloc use multiples of

$4$

$?$

$($

Check all that apply

$)$

Group of answer choices

Because each row is to contain

$4$

$$integers

Becaues the size of an integer is assumed to be

$4$

$$bytes

It is a coincidence

Because the number of rows in the array is to be

$4$
