Final answer:
Sociology is the systematic and scientific study of how societies and social interactions shape groups and individuals, with a focus on cultural patterns and societal roles, rather than individual behavior option (1).
Step-by-step explanation:
Sociology is the systematic and scientific study of society and social interaction. As a social science, it focuses not on individual behavior but on how society operates and evolves. This includes examining cultural patterns, social forces, and the influences they have on groups and individuals, as well as the roles and norms of behavior within cultural contexts.
Contrary to the idea that sociology takes the individual as its point of departure, one of sociology's primary concerns is how societies shape and are shaped by the members within them, collectively. Sociologists engage in theoretical perspectives to explain social events and interactions, which can be at the macro-level, considering the society as a whole, or at the micro-level, focusing specifically on individual interactions.
Therefore, the accurate assertion about sociology is that it has enhanced our understanding of the design of work, it focuses on the variety of roles within a culture and the norms of behavior in groups, which aligns with options 2 and 3 of the student's question.
