When only 'proportional' is used the without specifying which proportion it means that only the positive proportion is implied. Just as writing 20, means +ve and -20 means -ve 20. So the answer is B.

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

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.

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

The correct answer is only B.

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).
