HST will capture light from sources 20 times fainter (weaker) than those (sources) that...

whats wrong with A....

This is the line from this article onw hcih the above question is based:
Once positioned in space, the telescope will capture light from stars and other sources 20 times fainter than can be detected by ground-based instruments.

But to my dismay the correct option is not in the given options. reply2spg, wht is teh source?
