Correct choice is (d) Long

The best I can explain: Any number can be represented in the form of a whole number or a floating-point number. If it must be represented as a whole number, then there are many options depending upon the size of the number in question. Here the number 2146492440 should be represented using the long datatype since it has a range of -2147483648 to -2147483647.
