Resistance is directly proportional to the length and inversely proportional to the crossectional area. That's why correct answer is 'B' not both.

R= ρ(L/A).
Where ρ is a constant.
Where ρ is a constant.

Whether it doesn't specify direct or indirect proportion, we take it as directly proportional. So resistance is directly proportional to length. And the Answer is B.

Option D is the right one.
Ohms law V=IR.
R=V/I = AREA x Length/I.
R depends on AREA and Length.
Ohms law V=IR.
R=V/I = AREA x Length/I.
R depends on AREA and Length.

The answer is D.
Resistance is directly proportional to l and inversely proportional to A.
The word used is "proportional". So whether it is inversely or directly proportional. As long as it is proportional the answer is D.

Yes, I think D is suitable because there is not specified that directly or indirectly proportional.

@Karthick M.
Here, V = voltage not volume.
