- Total distance earth travel in 1 year ,let say d = 2(pi)r , where r : distance from sun to earth
- If the current distance from sun to earth is reduced by 1/4 then new distance = d` = 2(pi)(r/4) = d/4
- time = distance/speed.
If we make a assumption that speed of earth (revolution) remains constant , then the new time taken is 1/4th of earlier time. ( 1/4 of a year)
- So , I conclude option 2 is correct.

Note : I`m not a physicist. There is high chance my assumption might be wrong.

You may be proud, wise, and fine, but death will wipe you off the face of the earth as though you were no more than mice burrowing under the floor, and your posterity, your history, your immortal geniuses will burn or freeze together with the earthly globe.
