Hence this word completes the sentence in meaning and option B is correct.
Option A: 'Smashed' means 'violently broken into pieces'.
Option C: 'Dismantled' means 'made separate into different components'.
Option D: 'Frozen' means 'prevent assets from being used for a certain period of time'. 'Automobiles' are not assets that can be frozen, as they are directly "auctioned off".
These words are not relevant in meaning and context. Hence options A, C and D are wrong.
