Answer: C
Synergy is the interaction or cooperation of two or more organizations, substances, or other agents to produce a combined effect greater than the sum of their separate effects. As we can see, it says that not even one person could move the table. Even a strong person could only move the table an inch or two. But, cooperation is a very important aspect in life that can help us do things that we couldn't do ourselves. So, I am sure that the correct option is C, because the team effort allowed them to lift the table a move it to another location. Without this cooperation of each member, they wouldn't be able to move the table.
