Step-by-step explanation:
The most significant division within the discipline of sociology exists between the macro and micro sociology. Macro sociology focuses on studying society as a whole and understanding the larger structures and systems that shape human behavior. It examines issues like social inequality, institutions, and social change. Micro sociology, on the other hand, focuses on studying small-scale interactions between individuals and how those interactions shape society. It examines topics like face-to-face interactions, social roles, and identity formation.
So, the correct answer is option a.
