Answer: (B) They can be penetrated only with longer wavelengths such as radio and infrared.
Explanation:
A dark nebula is a type of interstellar cloud with such a high density that it "hides" the light of the background stars.
It should be noted that these nebulae are composed mostly of hydrogen (the star's primary fuel), and the absence of light (in the visible range of the electromagnetic spectrum) is caused by the interstellar solid dust that constitutes the cloud, which is why they are also called absorption nebulae.
However, <u>if powerful telescopes that detect at long wavelengths, such as infrared and X-rays, it is possible to observe through these nebulae and even observe the existence of young stars.</u>
