Read the given statements and conclusions carefully. Assuming that the information given in the statements 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 statements.
Statements:
1. All breads are donuts.
2. Some donuts are muffins.
3. No muffin is a fruit.
Conclusions:
I. No bread is a fruit.
II. Some muffins are breads.

​Statements:
1. All breads are donuts.
2. Some donuts are muffins.
3. No muffin is a fruit.

​Conclusions:

I. No bread is a fruit. (False, since no muffin is a fruit, it doesn't guarantee that no bread is a fruit, unless we can be sure that some breads are muffins, which is not stated).
II. Some muffins are breads. (False, there is no direct or indirect relation between muffins and breads).

So, ​Neither conclusion I nor II follows.

Thus, correct option is (a).
