array:array is a collection of elements
one dimensional array:
code:
       datatype arraysize[];
eg:
       int a[5];
two-dimensional array:
code:
       datatype array[rowsize][columnsize];
eg:
       int a[5][5];

static int [5]={2,3,4,5,6};
for one dimensional array
static int[3][3]={1,2,3,4,5,6};
for two dimensional array it consider as rows and columns

one dimensional array :
a={2}
two dimensional array 
b={2,3}

1-D array:

int a[4]={ 10,20,30,40};

2-D array:  # 2 columns and 2 rows
int a[2][2]= {  
       {100,200},                                           
       {300,400} };

Ans no. 4 is correct..

incase u have to initialise an array have more number of 
elements as i 100 or 200..

eg..

int a[50];
then u can use following functions:

**YOU CAN INITIALISE IT TO A PARTICULAR VALUE ONLY USING 
THE BELOW CODE..

int a[50];
int i;

for (i = 0 ; i < 50 ; i++)
{
  a[i] = 0;
}

similarly for 2D

for(i = 0 ; i < 50 ; i++)
{
   for(j = 0 ; j < 50 ; j++)
   {
      a[i][j] = 0;
   }
}
