Answer: A,B,C
Option A: a[2], a[1] is pointing to 1D array.
Number of elements between a[1] and a[2] is 4. $\therefore$ a[2] – a[1] = 4
Option D: It will be false since option A is true.
Option B: a[1][2] – a[0][3] = 15
Option C: a[0][10] – a[1][0]
a[0][10] = ((*a+0) + 10) = *a + 0 will point to 1D array adding 10 to it will point to a[2][2] array and de-referencing it will point to a[2][2][0]
$\therefore$ a[0][10] – a[1][0] = 30
