All needles are threads, All threads are boxes. All trees are boxes.
(A) No needle is tree.
(B) Some trees are threads
(C) Some boxes are needles
(D) Some trees are needles

Choose the correct answer from the options given below:

(A) No needle is a tree.

• We know that all needles are threads, and all threads are boxes, and all trees are boxes. However, there’s no direct relationship given between needles and trees. Therefore, this is not necessarily true.

(B) Some trees are threads.

• We know that all trees are boxes, and all threads are also boxes. However, the statements don't tell us that any tree must be a thread. Therefore, this is not necessarily true.

(C) Some boxes are needles.

• Since all needles are threads and all threads are boxes, this means that some boxes (specifically those that are threads) must be needles. This is true.

(D) Some trees are needles.

• We know that all trees are boxes, but there’s no information linking trees and needles directly, so this is not necessarily true.

Hence, the answer is C only.
