Which part of the integrated vehicle is designated to carry the necessary propellant and ultimately land on Mars?

Answer

The Starship upper stage

The fully assembled vehicle is composed of two primary stages: the Super Heavy first-stage booster responsible for the initial ascent thrust, and the Starship upper stage. It is this upper stage that is designed for the complex task of interplanetary travel. It houses the massive reservoirs intended to carry liquid methane and liquid oxygen across vast distances and is the component specifically intended to execute the landing maneuver upon arrival at destinations like Mars.
