All of the following could lead to a polygynous mating system EXCEPT…
large female territory size.
freedom of males from parental care.
spatial clumping of females.
an operational sex ratio skewed toward females
the polygynous mating system means one male mates with multiple females, this can happen when the number of females is more compared to males, or there are more females in a particular area ( clumping of females overall males, and females are spread but in a small area there are more females), in polygyny male cannot provide parental care to all offspring so polygyny arises when resources are unlimited so that female can take care of offspring so the answer is large female territory size., because if a female maintains large territory other females cannot enter the region so chances of polygyny is not there.
