The correct answer is: B.Cooling of the planet due to dust blocking sunlight

Meteor impacts, especially large ones, can eject vast amounts of dust, debris, and aerosols into the atmosphere. This material can block sunlight, leading to a temporary global cooling effect, often referred to as an "impact winter." The cooling can significantly disrupt climate patterns, reduce temperatures, and affect ecosystems, leading to changes in plant growth and animal behavior. This cooling can last for months or even years, depending on the size and scale of the impact.
