Katherine is visiting her partner's family for the first time and she has lots of questions. she already knows a lot about them, but she keeps asking about what the expectations will be. for example, she wonders how she should address family members (first names or using titles) and whether it is ok to come to breakfast in a pajama and robe. these expectations, which are not explicitly stated, are also known as rules.
a. overt
b. hidden
c. secondary
d. covert

The answer is d. covert rules.

Explanation:
