Answer 1

The Correct Option is C

Step 1: Understanding statements —
All Parathas → Sustainable.
Some Sustainable → Cost-Effective → All Cost-Effective → Popular.
Therefore, some Sustainable (and possibly some Parathas) → Popular.
Step 2: Evaluating conclusions —
I. Some Popular are Parathas → True, as some Parathas are Sustainable, and some Sustainable are Popular.
II. All Parathas are Popular → Not necessarily true.
III. Some Sustainable are Popular → True.
Step 3: Conclusion — Both I and III follow.
