Answer and Explanation:
The first situation presents a secondary group. Secondary groups are those formed by people with similar interests, who do not need constant contact to interact, but may have sporadic interactions based on the subjects of interest. As we can see, the group formed in the first situation has university students and Talha manages to interact with the engineering student, since Talha is very interested in this course and wants to study engineering at the university.
The second situation presents a psychological group where all members meet and associate frequently and on their own to achieve a common goal. In this situation we can see a group of cricket players, who want to work together to achieve the team's victory.
The third situation presents both the primary group and the secondary group. The secondary group can be seen when Ahmed has a professional desire in common with his uncle who is a lawyer, for Ahmed also wants to be a lawyer. The primary group is established by the intimate relationship between the members of Ahmed's family, where everyone meets frequently and has an influence on the personal and professional lives of the family members.
