Correct choices are marked in bold:

travel in straight lines and can bounce off surfaces --> TRUE, normally electromagnetic waves travel in straight lines, however they can be reflected by objects, bouncing off their surfaces

travel through space at the speed of light --> TRUE, all electromagnetic waves in space (vacuum) travel at the speed of light, $c=3\cdot 10^8 m/s$ )

travel only through matter --> FALSE; electromagnetic waves can also travel through vacuum

travel only through space --> FALSE, electromagnetic waves can also travel through matter

can bend around objects --> TRUE, this is what happens for instance when diffraction occurs: electromagnetic waves are bended around obstacles or small slits

move by particles bumping into each other --> FALSE, electromagnetic waves are oscillations of electric and magnetic fields, so no particles are involved

move by the interaction between an electric field and a magnetic field --> TRUE, electromagnetic waves consist of an electric field and a magnetic field oscillating in a direction perpendicular to the direction of motion of the wave

Electromagnetic waves are those waves that do not require a material medium for propagation.

Electromagnetic waves are those waves that do not require a material medium for propagation. Examples of electromagnetic waves include, visible light, x- rays, gamma rays etc.

The following are characteristics of electromagnetic waves;

travel through space at the speed of lightmove by the interaction between an electric field and a magnetic field.travel in straight lines and can bounce off surfaces.

Hence, electromagnetic waves are those waves that do not require a material medium for propagation.
