I'm sure most of us have heard the word <em>hijack </em>before, it's just a matter of remembering what it means.
The definition in Webster's Dictionary says, "to steal by stopping a vehicle on the highway."
We also see a similar definition on Google, "illegally seize (an aircraft, ship, or vehicle) in transit and force it to go to a different destination or use it for one's own purposes."
So in simple words, it just means to take over without permission.
Therefore, your answer would be A.
Hope this answer helped you out. :)
