The correct answer is - B. pull factor.

The intervening opportunity is considered as a significant pull factor for someone to migrate to a certain place. The pull factors are essentially things that are attracting someone to a certain place, thus migrate to that place because of the better living conditions in multiple aspects.

Intervening opportunity is the opportunity for settling at a certain place, less by distance or population pressure, at least at the starting point of the settling.
