I got D
Consider 5 persons v, w, x, y , z in the room.
U can eliminate
A - From above
B- From question stem - At most two people in the room recognize each other
C - From question stem - At most two people in the room recognize each other
E- This contradicts # of people who recongnize each other from the stem.
IN D - from stem : At most two people in the room recognize each other.
this is possible if two people know each other. Hence the conclusion !
A) Four people are in the room.
(B) No two people in the room recognize each other.
(C) At most one person in the room recognizes everybody else in the room.
(D) Anyone in the room who recognizes any other person in the room is also recognized by that person.
(E) Two people in the room recognize every one else in the room
How is D inconsistent with the argument, if there are EXACTLY 3 people in the room?
A B C
satisfies all conditions in the argument.
Even if there are exactly 3 guys in the room as you have said D holds.
If A knows B, then B knows A and as per the passage A cannot know C.
If A knows C, then C knows A and as per the passage A cannot know B.
THe passage says, at least one person can recognize everyone else in the room, but not necessarily be recognized by everyone else.
But D says anyone who recognizes the other two, will also be recognized by the other two and it is inconsistent.
