Option B is the correct answer because “juggernaut” means a huge, powerful, and overwhelming force, hence it is the same as a massive moving entity, hence it is correct.
Option A is incorrect because “miasma” means an unpleasant or unhealthy smell or vapour, which is not the same as a massive moving entity, hence it is incorrect.
Option C is incorrect because “jamboree “ means a large celebration or party, typically a lavish and boisterous one, hence it is incorrect.
Option D is incorrect because “typhoon” means a tropical storm in the region of the Indian or western Pacific oceans, which is not the same as a moving entity, hence it is incorrect.
