in the question its states tht current is directionaly proportional to voltage........so tht must be the only reason for the horizontal line.....
When current is directly propotional to voltage the graph passes through the origin. He was asking something else.

Search it in the PM and do let us know as well.
found it
ok so here it is
V is proportional to I
according to direct proportion rules their ratio must be constant
so V/I is a constant value
V/I is R so R remains constant
meaning whatever the current the pd will rise accordingly and hence the resistance would remain same
exploded diper is unfortunately correct

exploded diper is perfectly correct
I didn't quite get what you said.
How is it just a straight horizontal line? Why isn't it passing through the origin?
