correct answer is: option d (d)[Neither conclusion I nor II follows.]
Explanation: Let's analyze the statements and conclusions using a Venn diagram. Statement I: All shirts are trousers. This means the circle representing "shirts" is entirely contained within the circle representing "trousers." Statement II: No trouser is a jacket. This means the circles representing "trousers" and "jackets" do not intersect. Now let's evaluate the conclusions: Conclusion I: Some shirts are jackets. Since all shirts are trousers and no trousers are jackets, no shirts can be jackets. This conclusion is false. Conclusion II: Some jackets are trousers. Statement II clearly states that no trousers are jackets, meaning no jackets are trousers. This conclusion is also false. Therefore, neither conclusion I nor II follows logically from the given statements.

• Option a: [Only conclusion I follows] This is incorrect because conclusion I does not follow.
• Option b: [Only conclusion II follows] This is incorrect because conclusion II does not follow.
• Option c: [Either conclusion I or II follows] This is incorrect because neither conclusion follows.
