Can you help? I think this might be easy, but i keep getting it wrong. I personally think it's A, but i'm unsure about this type of question.

ganeshie8 · Answer

Why do you think A is the answer ?

ganeshie8 · Answer

There are many other factors that contribute to happiness right

Yes. But none of them make sense. Like D does not look like a good answer, C is obviously not a right answer, and B, i'm not sure... What do you think?

ganeshie8 · Answer

D is actually the correct answer
