C)about 2
D)greater than 6

Question

Quizplus · Accepted Answer

The most common redshift of quasars is approximately 2, meaning they are located at a distance of around 10 billion light-years away. This is due to the expansion of the universe, which stretches out the light emitted by these extremely distant objects, causing their wavelengths to shift towards the red end of the spectrum (known as redshift). While there are known cases of quasars with redshifts greater than 6, these are relatively rare and not representative of the overall population of quasars. Likewise, quasars with redshifts less than 0.1 or in the range of 0.1 to 0.5 are also not as common as those at redshifts of around 2.
