Correct option is D
From the above statement following Venn diagram can be drawn-

Conclusions 1.: Some rats are cats
· Since all cats are rats, it follows that some rats (specifically, those that are cats) are indeed cats. Therefore, Conclusion 1 follows.
Conclusion 2: All rats are goats
· There is no direct relationship indicating that all rats are goats, as the statements only confirm that all goats are cats and all cats are rats. This does not allow us to conclude that every rat is a goat. Therefore, Conclusion 2 does not follow.
Hence, the correct answer is (d) Only conclusion 1 follows.
