How is the take-off distance influenced on a grass runway in comparison to a paved surface?

The required distance for take-off will be increased. The braking performance on grass will not be as good as it would be on a paved surface

The required distance for take-off will be increased. The braking performance on grass will be better than on a paved surface

The required distance for take-off will be decreased. The braking performance on grass will not be as good as it would be on a paved surface
