for
from
to
none
Answer is Right!
Answer is Wrong!
The correct answer is C. to.
The word “bound” means “going or intended to go to a particular place.” In this case, the flying coach is going to Karachi. Therefore, the correct preposition to use is “to.”
The other options are incorrect because they do not make sense in the context of the sentence. The word “for” can be used to indicate a purpose or destination, but it does not make sense to say that the flying coach is “for Karachi.” The word “from” can be used to indicate a starting point, but it does not make sense to say that the flying coach is “from Karachi.” The word “none” is incorrect because it does not make sense to say that the flying coach is “none to Karachi.”
