Option A is the correct answer because ‘voyage’ means ‘a
long journey by sea or space’. Thus, option A is the right option.
Option B is incorrect because ‘odyssey’ means ‘a long eventful journey’. Although
it is relatively similar ‘odyssey’ is not specifically about a journey by sea
hence it is not an appropriate meaning for the given sentence.
Option C is incorrect because ‘safari’ means ‘a trip to hunt or observe animals
in their natural environment’. Thus, ‘safari’ is not similar in meaning to the
given word.
Option D is incorrect because ‘flight’ means ‘a journey through air or space’.
Thus, it is not a similar meaning to the given word.
