C.
The visible image shows a dark dust lane that blocks optical light, while the X‑ray image still reveals bright emission from the same region. X‑rays (higher energy, much shorter wavelength) penetrate dust much more easily than visible light, so dust that hides optical light can be effectively transparent to X‑rays. The other statements are absolute claims about X‑ray sources and optical emission that are not supported by the images.
