The correct answer is D) Hope.
The sun behind the candidate symbolizes hope.
When designers use a bright sun that shines in a poster, in this case, a political campaign poster with the candidate and behind it, the brilliant sun, it symbolizes hope, as the sun shines every morning in the expectancy of a bright new day. The sun shining is a representation of hope, a nerd ay, new opportunities to do things better than yesterday. And that is what the candidate wants to transmit, that he/she is the hope for a better future. He/she will do things better than the previous one.
