In which two places do divergent boundaries occur? land and oceans oceans and volcanoes volcanoes and lower mantle lower mantle and land

The correct option is;

Land and oceans

Explanation:

Divergent boundaries otherwise known as a constructive boundary is a feature that is liner in shape and occur between the spreading centers of two separating tectonic plates where also magma rising from the mantle forms a new crust

Rifts are formed in continents (land)by divergent boundaries which enlarge into rift valleys. Active divergent boundaries can be located in mid-ocean ridge tectonic plate and volcanic islands are formed by divergent boundaries.
