Looks like D.

If it is true, then more than 2 people in the room would recognize eachother and since the passage states "At least one person in the room recognizes everybody else in the room" then all these people would recognize that person which would conflict with "At most two people in the room recognize each other"

Although, I was also inclined to choosing B.

Let's take minimum of three people A B and C (There are at least three people in the room)

A knows B and B knows A (At most two people in the room recognize each other, i.e. no more than two people know each other)

A knows B and C (B and C don't know each other) or C knows A and B but they don't know C (At least one person in the room recognizes everybody else in the room)

so there can be All three people know each other so we conclude D
