What is the most accurate meaning of the word 'EFFLUVIUM' in the following context: "The swamp's effluvium was so strong that it could be smelled from a mile away"?
Correct: C
'Effluvium' refers to a discharge or emission of unpleasant or noxious substances. In this context, it describes something from the swamp that can be smelled, which aligns with 'discharge or emission'. The other options are incorrect because 'effluvium' is not typically associated with light, sound, or precipitation.
