to
for
towards
into
Answer is Wrong!
Answer is Right!
The correct answer is (A).
The word “bound” means “going or intended to go to a particular place.” In this sentence, the ship is going to Singapore, so the correct answer is “to.”
The word “for” can be used to mean “intended for a particular purpose,” but it cannot be used to describe the destination of a ship.
The word “towards” can be used to mean “in the direction of,” but it is not as specific as the word “to.”
The word “into” can be used to mean “to the inside of,” but it is not appropriate to use it to describe the destination of a ship.
