Step 1: Understanding the statements
1. All myntra $⇒$ Ajio means every myntra belongs to Ajio set.
2. Some Ajio is Flipkart means intersection between Ajio and Flipkart is non-empty.
3. Only a few Flipkart is Amazon means part of Flipkart belongs to Amazon, and some Flipkart are not Amazon.
4. No Amazon is Lenskart means Amazon and Lenskart have no intersection.
Step 2: Checking Conclusion I — Some Flipkart is not Lenskart
- From statement 3, we know some Flipkart are not Amazon.
- Since no Amazon is Lenskart, the non-Amazon Flipkart can still be Lenskart.
- But there is no direct restriction that all Flipkart are Lenskart.
- Possibility exists that some Flipkart are not Lenskart — this is logically valid.
- Therefore, Conclusion I follows.
Step 3: Checking Conclusion II — All Ajio is Lenskart is a possibility
- No statement directly restricts Ajio from being part of Lenskart.
- There is no contradiction between “All Ajio are Lenskart” and the given statements.
- Hence, this possibility exists.
- Therefore, Conclusion II follows.
Step 4: Final verdict
Both I and II logically follow from the given statements.
\[
\boxed{\text{Answer: (B) Both conclusions I and II followed}}
\]
