Common app legacy question

it asks
Have any relatives ever attended Georgia Institute of Technology?
does that include my brother who currently is a student of Georgia Tech?

I ask this because if I say yes to that question, they ask the number of degree that he received
he is undergraduate student so he doesn’t have any.

What should I do?

Does it not ask for graduation year (been a while since I applied)? If it does, put that he “got” a bachelors and list his future graduation year.

they only ask relationship, name, and number of degree, and year that he received his degrees.

That’s what I meant. If the question asks about people who have “attended,” list him and put the year he will graduate as the year he received his degree.
