A. hands and heads cannot really talk to each other ,so anything they "said" would be humorous.
Depending on the context, his remark could be humorous...the other answers dont really make sense
I do believe D is the right answer!
Human beings are naturally social creatures – we crave friendship and positive interactions, just as we do food and water. So it makes sense that the better our relationships are at work, the happier and more productive we're going to be.
Good working relationships give us several other benefits: our work is more enjoyable when we have good relationships with those around us. Also, people are more likely to go along with changes that we want to implement, and we're more innovative and creative.
What's more, good relationships give us freedom: instead of spending time and energy overcoming the problems associated with negative relationships, we can, instead, focus on opportunities.
