It is a type of passive diffusion, as the water travels along a concentration gradiant. As opposed to active transport, where the substances can pass against a concentration gradiant.

Osmosis does not require ATP so it is a passive transport.
Osmosis is a form of passive transport. Water molecules are small enough to move freely across the plasma membrane without the use of cellular energy.

Nope. Osmosis (the diffusion of water) is a form of passive transport because no energy is required and the molecules go from areas of high concentration to areas with a lower concentration.

Yes, osmosis is a passive process, as it does not require input energy in the form of ATP.

Osmosis is the diffusion of water trough a selectively permeable membrane. However, water passes quite easily across most membranes. So it's mostly known as passive transport
