In shallow depth chamber, the depth of the cavity provided in the piston is quite small. The squish is negligible due to very large cavity diameter. All these types are direct-injection chamber.

Combustion Chambers
Combustion chambers are used in internal combustion engines to burn the fuel-air mixture and generate power. There are different types of combustion chambers, such as shallow depth chambers, hemispherical chambers, cylindrical chambers, and toroidal chambers.
Negligible Squish
Squish is the term used to describe the movement of the fuel-air mixture towards the center of the combustion chamber during the compression stroke. The squish effect is created by the piston moving towards the cylinder head, which compresses the fuel-air mixture and forces it towards the center of the chamber.
Shallow Depth Chamber
A shallow depth chamber has a small distance between the piston and the cylinder head, which results in a low squish effect. The shallow depth chamber has a flat combustion chamber design, which reduces the turbulence of the fuel-air mixture during the compression stroke. As a result, the combustion process is slower, and the engine generates less power.
Conclusion
The correct answer is option A, shallow depth chamber, which has negligible squish due to its low distance between the piston and the cylinder head. This type of combustion chamber has a flat design, which reduces turbulence and slows down the combustion process.
