C)Greater, in order to have more time and space to react.Correct
# Explanation
When weather or environmental conditions are unfavourable (rain, fog, snow, etc.), visibility decreases and the pavement becomes more slippery, increasing braking distances. Therefore, you should increase the separation from the vehicle in front to have more time and space to react to any unexpected event. This greater distance is essential for your safety and that of others.
