Introduction:
The question asks us to identify the relationship between 'War' and another word, similar to the relationship between 'Smoke' and 'Pollution'. To find the correct answer, we need to understand the connection between the given words and determine which option best reflects that relationship.

Understanding the Relationship:
To identify the relationship between 'Smoke' and 'Pollution', we can analyze the cause and effect relationship between the two words. Smoke is a byproduct of certain activities such as burning, and it is a major contributor to air pollution. Therefore, the relationship between 'Smoke' and 'Pollution' is that smoke causes pollution.

Applying the Same Relationship:
Now, let's apply the same cause and effect relationship to the word 'War'. War is a conflict between nations or groups that involves violence and destruction. Based on this understanding, we need to find an option that represents the effect or consequence of war.

Options Analysis:
a) Victory: While victory can be a result of war, it does not represent the relationship between war and another word in the same cause and effect manner as 'Smoke' and 'Pollution'.

b) Treaty: A treaty is an agreement or contract made between nations to resolve conflicts peacefully and avoid war. Although a treaty can be a result of war, it does not reflect the cause and effect relationship between war and another word.

c) Defeat: Defeat can be an outcome of war, but it does not represent the cause and effect relationship we are looking for.

d) Destruction: Destruction accurately reflects the relationship between war and another word. War often leads to severe destruction of infrastructure, cities, and lives. Similar to how smoke causes pollution, war causes destruction.

Conclusion:
Based on the analysis, the correct answer is option 'D' - 'Destruction'. War is related to destruction in the same way as smoke is related to pollution because war causes destruction, just as smoke causes pollution.
