I think it's A, Diffraction.
Reflection is basically throwing back light without absorbing it, so that's false.
Refraction is like diffraction, but it's when light passes through something like water with or without touching the edge that it bends (I don't know how to explain it xD)
And I think transcription is something to do with DNA or genes, so that's automatically false.
If someone can confirm this, that'd be great! I hope this helps! :)
