The Proton K/M, Zenit 3SL, and PSLV are launch vehicles.

• A. They are weather satellites
• B. They are launch vehicles
• C. They are ground stations
• D. They are rocket fuels

Answer: (B)

A launch vehicle is the rocket system that carries payloads from Earth's surface into space, providing the thrust and staging needed to reach orbit. Proton K/M, Zenit 3SL, and PSLV are all launch vehicles because they are designed to lift satellites or other payloads into space and then deploy them. They are not weather satellites themselves (those are payloads carried by a launch vehicle), not ground stations (infrastructure for tracking/communication), and not rocket fuels (propellants power the rocket inside the vehicle).
