Harper is 35 years old and has just enrolled in his first university course. on the first day of class, he looks over the individuals in the room and sits next toanother male student who appears to be in his early 30s. in this case, harper has likely classified the other student
a. using a self-serving bias.
b. as someone who has more university experience than harper.
c. as a member of his ingroup.
d. as the teaching assistant for the class

Option C

Explanation: We can use age to classify people into groups. Some people are talented in identifying the age of people by looking at there faces or attitude and then classify them under a group they have predefined.

Harper is 35 years or we can say he is someone in his thirties (30+), we can say harper belongs to a group of people with the age of 30+.

He was able to identify a class mate of age within this range and sit next to him. This process explains harper classification of people based on age and obviously ,he needed to sit next to someone of his age to get along since its his first course in the university .

So we can say harper classified the other student as a member of his ingroup (age of thirties)
