For a projectile with
initial velocity=vi
projection angle = θ with horizontal
The time of flight
=2visin(θ)
If time is doubled with θ unchanged, vi is doubled.
From
range = vi²sin(2θ)/g
you can figure out the increase of the range when time (and vi) is doubled.
for given angle of projection if time of flight is doubled horizontal range will increase to A FOUR TIMES B thrice C once D TWICE
