The Correct Option is D

To solve this logical reasoning question, we need to analyze the given statements and evaluate the truth of the options.

Given statements:

• All needles are threads.
• All threads are boxes.
• All trees are boxes.

Based on the above statements, let's examine the validity of each option:

Option Analysis:

1. No needle is tree:
   • There is no direct information about the relationship between needles and trees.
   • While needles and trees both belong to the category of boxes, nothing is stated about their direct relationship.
   • Therefore, this statement is inconclusive.
2. Some trees are threads:
   • From the given statements, all trees and threads are categorized under boxes but do not share a direct relationship.
   • No information supports the existence of a relationship between some trees and threads.
   • Hence, this statement is false.
3. Some boxes are needles:
   • According to the statements, all needles are threads, and all threads are boxes.
   • This means every needle is definitely part of the boxes.
   • Thus, the statement "Some boxes are needles" is true.
4. Some trees are needles:
   • Similar to the analysis for Option A, there is no direct information linking trees and needles.
   • The statement cannot be deduced; therefore, it is false.

Conclusion:

The correct answer is C only because option C is the only statement that can be definitely concluded based on the given information.
