Correct option is B
Statements:
All computers are laptops.
- This means every computer is a laptop. However, not all laptops need to be computers.
All laptops are smartphones.
- This means every laptop is also a smartphone. So, from statement 1, all computers are smartphones (since all computers are laptops, and all laptops are smartphones).
Some smartphones are tablets.
- This means there is some overlap between smartphones and tablets, but it does not specify the relationship between computers and tablets.
Analyzing the conclusions:
Conclusion I: Some tablets are computers.
- From statement 3, we know that some smartphones are tablets.
- From statements 1 and 2, we know that all computers are smartphones, but there is no direct link stating that any of those smartphones (which are computers) are tablets.
So, Conclusion I does not logically follow. There's no necessary overlap between tablets and computers based on the given statements.
Conclusion II: Some smartphones are computers.
- As per statement 1, all computers are laptops, and according to statement 2, all laptops are smartphones. Therefore, all computers are smartphones, which means some smartphones are indeed computers.
So, Conclusion II follows.
Final Answer:
Only Conclusion II follows.
Correct answer: B. Only conclusion II follows.
