The answer is C (EF and HI)
This is because both lines pass through the centre A, meaning both are diameters. Hence, they are equal in length.

Keep in mind that we need to swap the variables because a function and its inverse are symmetrical about the line y=x. See the graph below.
C: is the speed of light (3*10^8 m/s) and it is squared (raised to the power 2) in this equation.
plane 1 travels 395 miles in 1 hour
plane 2 travels 422 miles in 1 hour
together, they travel (395+422) 817 miles in 1 hour
to have 2451 miles between then, they'd need to travel

so in 3 hours, they'll be 2451 miles apart
