Given parameters:
- Initial diameter of brass billet (D1) = 100 mm
- Final diameter of brass billet (D2) = 50 mm
- Working temperature (T) = 700°C
- Extrusion constant (K) = 250 MPa

Formula:
- Force required for extrusion (F) = K x π/4 x (D1^2 - D2^2)

Calculation:
- F = 250 x π/4 x (100^2 - 50^2) = 2.72 MN

Therefore, the correct answer is option B.

Explanation:
- Extrusion is a metal forming process in which a billet is forced to flow through a die to obtain a desired shape and size.
- The force required for extrusion depends on the material properties, working temperature, and extrusion constant.
- The extrusion constant is a measure of the resistance of the material to deformation and is determined experimentally.
- The formula for force required for extrusion involves the extrusion constant, cross-sectional area, and length of the billet.
- In this case, the initial and final diameters of the brass billet are given, and the force can be calculated using the formula and given parameters.
