As per the terminology used for timber, the angle between the face of the cutter and the line joining the cutting edge to the centre of the block is called as:

Correct option is A

Rake Angle
The angle between the face of the cutting tool and a plane parallel to its base.
If the inclination is towards the shank, it is called the back rake angle.
If measured along the side, it is known as the side rake angle.
Lip Angle
The angle between the face and the flank of the cutting tool.
A larger lip angle makes the cutting edge stronger and more durable.
Relief Angle
The angle between the flank of the tool and a perpendicular line drawn from the cutting edge to the base of the tool.
It prevents excessive friction between the tool and the work surface.
Cutting Angle
The angle between the face of the cutter and the line joining the cutting edge to the centre of the cutter block.
This angle influences the cutting efficiency and quality of finish.
