John forgot his debit card pin so he called the bank executive. To maintain the privacy of the account the executive told him a way to get his pin back. The executive gave John a code x=1010 and told him that he will get his pin back after decoding the question. He wants your help because he doesn't have knowledge about logical operations. Which of the following options results in the value of the last 1-bit?
For eg: x = 1100
Here the value of the last 1 from left is 2^2 = 4. So option giving value = 4 will be the answer.
