the jovian problem refers to?

Question

The term "Jovian problem" refers to which of the following aspects related to the Jovian planets?
a. The high speed at which the Jovian planets rotate on their axes
b. The large number of satellites that orbit each Jovian planet
c. The existence of rings around the Jovian planets
d. The excess heat radiated by the larger Jovian planets
e. The apparently short period of time that disks exist around stars from which planets can form

e. the apparently short period of time that disks exist around stars from which stars can form
The problem is that Jovian planets seem to be very common. However, protoplanetary disks tend to evaporate quickly, typically within a million years, by radiation of the central star and nearby massive stars. The timescale is too short for Jovian planets to grow by collision of planetesimals as smaller planets do.
The solution seems to be that Jovian planets can grow by direct gas accretion without forming rocky planetesimals first.

D. We don’t know how long disks exist around stars. Jovian planets differ from others in that the amount of heat they radiate is higher than the amount they receive.
