The correct answer is 6.
The clearest way to determine this is by creating a table of possible hand shaking. If we label the people A-D, the following are the ways they can be combined: AB AC AD BC BD CD
There are no other combinations.
There are **6 handshakes between **four people in the room. ;
The total number of handshakes among four people is 6, as each person shakes hands with every other person exactly once. This can be calculated by listing all unique pairs or by using the combination formula. Therefore, the answer is A. 6.
