Read the given statements and conclusions carefully. Assuming that the information given in the statement is ture, even if its appears to be at various with commonly known facts, decide which of the given conclusions logically follow(s) from the statements.

(iii) No dogs are animals.

(iv) All mammals are dogs.

Statements:

(a) All dogs are mammals.

(b) No animals are dogs.
