If a program requires a dynamically allocate two-dimensional array, you would allocate the memory by using

a. p1 = new int*[numRows];
for(int i=0; i < numRows; i++)
p1[i] = new int[numColumns];
b. p1 = new int*[numRows][numColumns];
c. p1 = new[numRows][numColumns]int;
d. none of the above

a. p1 = new int*[numRows];
for(int i=0; i < numRows; i++)
p1[i] = new int[numColumns];
