Vector quantity is defined by direction as well as magnitude both
so now lets discuss all option
1) distance = it is total path length between two points so there is no direction needed in it so it is scalar
2) Speed = it is ratio of total distance covered and total time, so it also do not require any direction.
3)velocity = it is ratio of displacement and time, and displacement is always given with direction so velocity is a vector quantity
4) time = time is the measurement of the interval of two events and we do not require any direction in it so its a scalar quantity.
