Answer:
The correct answer option is: Tiredness.
Step-by-step explanation:
This excerpt is taken from Frankenstein, by Mary Wollstonecraft Shelley, in which the author has made use of the word languor in context of tiredness or exhaustion.
The literal meaning of the word languor is 'tiredness' or 'inactivity' which can be guessed as the author used two similar words in a row: languor and extreme weakness.
Therefore, the correct option is tiredness.
