Sedimentary rocks can become metamorphic rocks.
Metamorphic rocks can be broken into sediments that could become sedimentary rocks.
Igneous rocks can become metamorphic rocks when exposed to heat and pressure.
In order for a sedimentary rock to become a metamorphic rock it must be melted to magma first.
Existing sedimentary rocks can be broken into sediments and then become a new sedimentary rock.

Answer 1

The incorrect statement is: "In order for a sedimentary rock to become a metamorphic rock it must be melted to magma first." This statement is false because metamorphism can occur in a solid state, without the rock being fully melted into magma.
