Concept:
Values and norms are closely related elements of culture in sociology.
Step 1:
Values are broad ideals and beliefs about what is considered desirable or important in society.
Step 2:
Norms are rules or expectations that guide behaviour according to accepted social values.
Step 3:
Since norms are based on social values, they can be seen as reflections of those values.
\[
A \text{ is correct}
\]
Step 4:
Hygiene-related norms reflect the value society places on health and cleanliness.
\[
R \text{ is correct and explains } A
\]
Step 5:
Therefore, both Assertion and Reason are correct, and Reason correctly explains Assertion.
\[
\boxed{\text{(1) Both (A) and (R) are correct and (R) is the correct explanation of (A)}}
\]
