The correct answer is C. Floating point unit and coprocessor unit.

A coprocessor is a specialized processor that assists the main processor in performing certain tasks. The two major sections in a coprocessor are the floating point unit and the coprocessor unit.

The floating point unit (FPU) is responsible for performing floating point calculations. Floating point numbers are numbers that can have a decimal point, and they are used to represent real-world quantities such as distances, weights, and temperatures. The FPU is much faster than the main processor at performing floating point calculations, which is why it is often used in applications that require a lot of floating point processing, such as scientific computing and video games.

The coprocessor unit (CPU) is responsible for performing all other tasks that are not handled by the FPU. This includes tasks such as integer arithmetic, logical operations, and memory management. The CPU is typically much faster than the FPU at performing these tasks, which is why it is used for most of the processing in a computer.

In conclusion, the two major sections in a coprocessor are the floating point unit and the coprocessor unit. The FPU is responsible for performing floating point calculations, while the CPU is responsible for performing all other tasks.
