Answer: B
Idiom - 'made possible by [something]' and never 'made possible because...' ---> eliminates A, D and E

Essentially, the statement is saying, "field of physical cosmology is made possible by Einstein's theory of relativity; field of physical cosmology is made possible by the better ability to observe [farther]...'. So, for concision's sake, we say 'made possible by both [X] and [Y]'.
This can also be rewritten as 'Both [X] and [Y] made [Z] possible' ---> hence, B is correct.

+1 B

Split between "Because of", "by", and "as a result" --> demands a "by"
Answers left: B&C
two parallel causes require a "both". Thus, "B"
