Answer:

In the verbal reasoning category, the relationship between the words "Obscene" and "Filthy" is similar to the relationship between the words "Wreck" and "Destroyed."

Just as "Obscene" and "Filthy" are synonyms that both describe something dirty or offensive, "Wreck" and "Destroyed" are words that are also related in meaning. A wreck is a damaged or ruined structure or vehicle, and when something is wrecked, it is typically left in a destroyed or severely damaged state.

Therefore, the correct answer is: Wreck : Destroyed

This analogy highlights the relationship between the pairs of words in terms of their similarity in meaning and usage, making it a common type of question in verbal reasoning tests.
