Clearly ans is d.
1<<0 times is 0001.so in decimal 1.
1<<1 times is 0010.so in decimal 2.
1<<2 times is 0100.so in decimal 4.
1<<3 times is 1000.so in decimal 8.
1<<4 times is 0001 0000.so in decimal 16.
thus it becomes 1,2,4,8,16.

o in binary is 0 only...
and wen it is lft shfted it remains same...
1 in binary is 01 >> makes it 010 i.e 2
nd so on...
