Resistance is directly proportional to length and inversely proportional to area.

The answer should be "B" as resistance increases with length but decreases with cross sectional area.

Resistance is directly proportional to length and inversely proportional to area.
R ∝ l/A.
R = ρl/A.
Here ρ is electrical resistivity.
R ∝ l/A.
R = ρl/A.
Here ρ is electrical resistivity.

Resistance is directly proportional to the length of conductor (more the length more will be the resistance) and is inversely proportional to the area of the conductor (more the area less will be the resistance).

It should be option B as R is proportional to the only l.

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.
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.

Here, Proportional means directly proportional.
Then answer is B.
Then answer is B.
