selection a.

Explanation:

If we assume that the orbit is circular, then the length of the semi-major axis becomes the radius and the circumference is:

#C = 2.44pixx10^6"km"#

Convert days to hours:

#15.945"days"(24"hr"/"day") = 382.68"hr"#

#V = C/t#

#V = 2.003xx10^4km/hr#

The closest number is selection a.
