I'd guess as many options as there are stations. :)  It all depends on 
what is available.

Remember that one of the major reasons for diversity is that the 
antennas be spatially separated from each other to neutralize the 
effects of selective fading.  When we receive both a direct and 
reflected signal from the DX station, the two arrivals can be more 
nearly in phase at one antenna location when they are more out of phase 
at the other antenna.  That's not the only reason for diversity, of 
course, but it's a major one.

Some hams believe that differently polarized antennas should be used, or 
that one antenna have a high angle major lobe and the other have a low 
angle major lobe. Some of the best 160M ops I know rearrange their 
stations for 160M events by bringing all of their antennas to a big 
patch panel so they can switch between them to RX any signal that 
they're trying to work. It is well known, for example, that signals for 
a given path may be high angle at one part of the opening and low angle 
at another time.
