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.

Yes, you are Right @Sophia.

Resistance is directly proportional to length and inversely proportional to area. So the correct answer is B.

The Correct option is D, Because it does not mention whether it is directly or inversely proportional.

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

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.

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

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