How does the replacing grass with cement and asphalt impact flooding after a heavy rain?

Grass and soil absorb some rainwater, allowing it to seep into the ground. Cement and asphalt are mostly impermeable, so replacing grass with them prevents water from soaking in. More rainwater stays on the surface and can contribute to flooding, so the correct choice is “It prevents rainwater from seeping into the ground, causing water to stay on the surface.”
