Correct Option: C

The earthquake-cum-tsunami packed such fury that it has moved Japan’s main island, Honshu, by about 8 feet. It’s also caused the Earth’s axis to wobble by about 4 inches something that experts say will lead to the shortening of the day by 1.6 microseconds, or just over a millionth of a second. These very tiny changes happen because of changes in the speed of rotation of the Earth as surface mass gets shifted around in earthquakes. The Chilean quake of 2010 too shortened the day by 1.26 microseconds and changed the axis by 3 inches.
