However, the given answer mentions that `PRAHAR` is a short-range surface to surface missile, which contradicts this option.

Option 2 suggests that the missile is a long-range surface to air missile. This means that `PRAHAR` would be capable of engaging airborne targets from a long distance. However, this option is not the correct answer because the given answer specifies that `PRAHAR` is a short-range surface to surface missile.

Option 3 correctly states that `PRAHAR` is a short-range surface to surface missile. A surface to surface missile is a missile that is launched from one surface location, such as the ground, and is intended to strike a target on another surface location. `PRAHAR` falls into this category and it was indeed test fired by DRDO in 2011.

Option 4 claims that `PRAHAR` is a long-range surface to surface missile. However, this contradicts the given answer which states that
