2) 3 arrays every array with 6 elements (2 by 3 array). Two rows and three columns.

3 arrays and if every array has 6 elements the total number of elements = 3*6 = 18. I think this is the answer.

It is 3d array so total 9 element so every element take 2 byte size because it is int type array so answer is 18.

Well, its because; it is a 3D array with dimensions 3,2,3 so simply its get multiplied 3*2*3 = 18 i.e: Option C.
Note: In C# int requires 4 bytes of memory.

It is third dimension array right?
Then how can we decide it's length as 18?

3D array means 3 dimensional you can see the question in the square braces two commas is there that's the reason its called 3 dimesion array and 18 is the answer simply multiplied.
