Answer: Option C
A hybrid computer is a type of computer that combines the features and capabilities of both analog and digital computers. It uses analog technology to measure and process continuous physical variables, and digital technology to process discrete data and perform complex calculations.
Let's understand the properties of analog and digital computers in more detail:

• Analog computers: An analog computer is a type of computer that uses continuous physical phenomena, such as electrical, mechanical, or hydraulic, to solve problems. It represents variables as continuously varying physical quantities, such as voltage, current, or position. Analog computers are useful for tasks that require high-speed processing of continuous data, such as simulation of physical systems, control of industrial processes, and weather forecasting.

• Digital computers: A digital computer is a type of computer that uses binary digits, or bits, to represent data and perform operations. It processes discrete data and performs arithmetic and logical operations using a fixed set of instructions. Digital computers are useful for tasks that require high accuracy and precision, such as scientific calculations, data analysis, and general-purpose computing.

A hybrid computer combines the advantages of both analog and digital computers to solve complex problems that require both continuous and discrete data processing. For example, a hybrid computer can be used for real-time control of physical systems, such as aircraft, missiles, and submarines, where it needs to process both continuous and discrete data.
Hence, the correct answer to the given question is option C, analog and digital computers.
