First, notice 2014 is even, so first and third answer are out because they are odd.
Next, notice the bits that differ in the remaining two answer choices(second bit from the left having value of 512) and see which choice is correct.
Calculate 2014 minus 1024(the leftmost bit value) to see if difference leaves enough to subtract 512. If yes, choose answer with bit on; if no choose answer with bit off. Since the answer is yes, then the 512 bit must be on, so the correct answer is the fourth choice.
