The correct answer is: (A) Jagged Array

Explanation:

In C language, array dimensions and sizes must be known at compile time for static allocation.

Let’s look at the options:

(A) Jagged Array – ❌ Not possible statically

• A jagged array (also known as an "array of arrays" where each sub-array can have different lengths) is not possible statically in C.
• C supports arrays of pointers to achieve jagged arrays dynamically, but you cannot declare a jagged array statically since each row would need to have a different size, and static arrays in C require fixed dimensions.

Example (dynamic jagged array):

int *arr[3];

arr[0] = malloc(2 * sizeof(int));  // 2 elements

arr[1] = malloc(4 * sizeof(int));  // 4 elements

arr[2] = malloc(3 * sizeof(int));  // 3 elements

(B) Rectangular Array – ✅ Possible statically

• A typical 2D array with the same number of columns in each row.

int arr[3][4]; // 3 rows, 4 columns

(C) Cuboidal Array – ✅ Possible statically

• A 3D array (same size for all dimensions).

int arr[3][4][5]; // 3 layers of 4x5

(D) Multidimensional Array – ✅ Possible statically

• General term for arrays with 2 or more dimensions.
• C supports statically declared multidimensional arrays:

int arr[2][3][4]; // 3D

Final Answer: (A) Jagged Array
