Explanation
The manufacturers’ goal is to make certain items dedicated collectibles, so they would do something to make them more rare or special. Choices (E) and (F) are synonyms that mean activate, but the blank refers to the trucks themselves and so you can eliminate these choices.
Choice (C) can be eliminated because it means examine and doesn’t match the needed meaning. Choice (B) is also irrelevant to the context of the blank. That leaves choices (A) and (D), both of which mean to make more rare and produce equivalent, appropriate sentences.
Hence options A and D are best fit!
