The correct options are B: increased competition and D: loss of habitat.
There are many causes of habitat loss, including a land conversion for development from growing populations, mining for materials, harvesting lumber for paper products, and of course, agriculture.
Because competition is often more intense as population size increases the effect of the competition is often density-dependent, that is at higher population density competition increases. Will adversely affect survivorship and births, i.e. population size.
