When you run the code, you receive the following error message: “Cannot implicitly convert type ‘object” to ‘inf.
An explicit conversion exists (are you missing a cast?).”
You need to ensure that the code can be compiled.

A.
var2 = ((List<int>) array1) [0];
B.
var2 = array1[0].Equals(typeof(int));
C.
var2 = Convert.ToInt32(array1[0]);
D.
