“Incinerated” means to destroy (something, especially waste material) by burning.
Hence option D is the correct and obvious answer because “burnt” means something that has been destroyed by fire, hence it is the correct answer.
Option A is incorrect because “destroyed” means damaged, but it doesn’t necessarily mean damaged by fire, hence it is incorrect.
Option B is incorrect because “shaken “ means something that has vibrated or trembled, hence it is incorrect.
Option C is incorrect because “bombed” means fire explosives have been used, but burning down can be carried out without explosives as well, hence it is incorrect.
