A national S opened a candy store. One day, S decided to increase the unit price of nougat and toffee by 2.9 yuan and 1.8 yuan respectively; on the same day, an F-222 fighter plane of the country's air force crashed. One month later, S again Doubled the unit price of toffee; at 14:00 on the same day, a passenger plane C died shortly after takeoff. Two months later, S issued a statement on the price of candy, saying that the price had not been adjusted and the unit price of nougat was increased by 1.2 yuan; the same day A passenger plane of an airline of Ding Guo crashed near the northwest of the country. It can be seen that S uses the price of candy as a weapon to specifically target overseas spacecraft. If the following options are true, what would best support the above conclusion? ['When the aircraft is manufactured, the internal program is set to actively receive the candy pricing information of S. When it encounters a specific price, it crashes.', 'Not only foreign aircraft but also domestic aircraft crashed; not only military fighters but also civil passenger aircraft.', 'S has a close relationship with a multinational terrorist organization, and has learned the detailed plan of the terrorist attack before adjusting the price of candy.', 'S implanted bombs in candy sold to overseas pilots, exploded immediately after biting.']
