Read the given statement(s) and conclusions carefully. Assuming that the information given in the statement(s) is true, even if it appears to be at variance with commonly known facts, decide which of the given conclusions logically follow(s) from the statement(s).
Statements:
All cakes are breads.
All cakes are pastries.
Conclusions:
(I) Some breads are pastries.
(II) All pastries are cakes.

Given:

​Conclusions:
(I) Some breads are pastries.
(II) All pastries are cakes.

From the given statement following Venn diagram will  be - 

Conclusion (I): Some breads are pastries.
Since all cakes are breads and all cakes are pastries, the cakes represent an overlap between breads and pastries.
So, there exists at least some breads (the cakes) that are pastries.
Therefore, conclusion (I) follows.
Conclusion (II): All pastries are cakes.
From the statements, cakes are inside pastries, but there's no information that pastries are inside cakes.
So, it cannot be concluded that all pastries are cakes.
Therefore, conclusion (II) does not follow.

Correct answer is (b)​​
