The answer would be none of the above since if y was = 10, then x would have to be 10^10. 

log x means what value you have to raise 10 to to get x, so if y = log x = 10, then x = 10^10

\(y = log_a x\\\\x = a^y\)

\(10 = log_{10}~ x\)

Therefore,

\(x = 10^10\)

Your answer is 10^10.

None of your answer choices match.
