What types of pumps are found in each fuel tank?

The presence of multiple types of pumps in each fuel tank is essential for maintaining fuel flow and pressure under varying operational conditions. The correct choice highlights the diversity of pump types, which serve specific purposes critical to the fuel system's functionality.

Boost pumps are used to assist in maintaining fuel pressure and ensuring that fuel reaches the engine, especially during startup and low-demand scenarios. Primary jet pumps are part of the system that helps transfer fuel from tank to tank or to the engine based on the aircraft's fuel management needs. Additionally, low and high-pressure pumps play vital roles in regulating fuel delivery under different engine operating conditions. The inclusion of transfer jet pumps allows for the effective movement of fuel between tanks to maintain balance and optimize fuel usage throughout the flight.

This comprehensive array of pumps ensures reliability and efficiency in the fuel management system, catering to the varying demands placed on it during operation. The other options fail to account for the full range of components necessary for effective fuel tank operation, focusing either on singular types of pumps or omitting essential functions necessary for the overall fuel management strategy in aviation fuel systems.
