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) Some cats are rats.
(2) All rats are dogs.
(3) All dogs are monkeys.
Conclusions:
(I) Some monkeys are cats.
(II) All monkeys are rats.

​Statements:
(1) Some cats are rats.
(2) All rats are dogs.
(3) All dogs are monkeys.

According to the given information, Venn diagram will be:

Conclusions:
(I) Some monkeys are cats: (True)
Since some cats are rats, and all rats are dogs (which are also monkeys), so this conclusion follows.
(II) All monkeys are rats: (False)
Not  true, as not all monkeys are confirmed to be rats based on the given statements.
Thus, the correct option is (b) Only conclusion I follows.​​​​
