All numbers in the expression are written in scientific notation, so it is simply a matter of performing the operation. When multiplying numbers in scientific notation, you multiply the coefficients and add the exponents. Using D as an example:
(5.4617 x 10^8) x (5.2951 x 10^-5) = (5.4617 x 5.2951) x 10^(8-5) = 28.915 x 10^3 = 2.8915 x 10^4.

Therefore, the answer in scientific notation is 2.8915 x 10^4, which is in choice D.
