Best Explanation for the extinction of Dinosaurs

New weather patterns which meant bad storms and cold temperatures on earth due to continents drifting outwards towards the North and South. Hence, plants that cannot withstand the cold temperatures might have died off first, followed by plant-eating dinosaurs and meat-eating dinosaurs.
Dinosaurs travelling to new lands might have caught diseases that they have no defences against. They could too, brought new diseases with them that their new neighbours could not fight.
Changes in the sea level causes dinosaurs to either drown or die as their homes dried up.
The Sun might have a hidden 'twin' called "Nemesis" which do not give out much light, it might have disturbed the Oort clouds on its orbit and have comets sent speeding toward earth due to the Death Star theory.
Due to Planet X, a mystery planet in the solar system which scientists think that on its own strange route, races through the Oort Clouds hence setting those comets into motion.
