Solar flares are sudden bursts of energy and particles from the Sun's surface caused by magnetic field reconnection. They can emit X-rays and UV radiation that reach Earth within minutes, potentially disrupting satellite communications, GPS systems, and power grids. The other options are not valid solar phenomena.

The Sun is the closest star to Earth at an average distance of about 93 million miles (150 million km). All other stars are light-years away. Titan and Triton are moons (of Saturn and Neptune respectively), while Pluto is a dwarf planet in our solar system - none are stars.

Energy generated in the sun's core takes approximately 100,000 to 170,000 years to reach the surface via radiative diffusion, not 'almost a million years'. While this is a long time, 'almost a million' is a significant exaggeration.

Nils Bohlin invented the three-point seat belt while working at Volvo in 1959. His design became the industry standard and has saved countless lives worldwide. Volvo made the patent freely available to all manufacturers.

Douglas Engelbart invented the computer mouse at Stanford Research Institute in the 1960s. His patent was filed in 1967 and the device was demonstrated in the famous 'Mother of All Demos' in 1968.

John Harington invented the first flush toilet in 1596 for Queen Elizabeth I. While others like Alexander Cumming and Thomas Crapper made improvements later, Harington is credited with the original invention.

Niels Christensen invented the modern O-ring and received a patent in 1937. The invention became critical during WWII for sealing aircraft and military equipment. Thomas Edison is incorrectly associated with this invention.
