Q1. All aspects of population are discussed in which of the following subjects or sciences?
A Cartography
B Ecology
C Demography Correct
D Oceanography
Explanation
Demography is the systematic study of population, including size, distribution, density, growth, birth rate, death rate, migration, age structure, and related social characteristics. Cartography deals with making and studying maps, so it may represent population spatially but does not discuss all aspects of population. Ecology studies relationships between organisms and their environment. Oceanography studies oceans and marine processes. Since the stem asks for the subject or science that covers all aspects of population, demography is the precise answer.
