Answer:
D or the fourth option
Step-by-step explanation:
Basically the sentence that is highlighted I'm assuming thats the sentence there talking about in, the question is talking about Mars and Earth being similar, they say that they are like brother and sister which can mean they are really similar.
Now we look at the options, the first one states media based on basic facts.
The second option states a photo of Mars, now this option has nothing about Earth cross it off.
The third one, a video if mars is really red, I think the title openly gives away that its probably not going to have anything about Earth so cross that off.
The fourth, its comparing the sizes something we are looking for.
The fifth a photo of Arizona, a state in the US. So we can imediatley cross that off.
Using my deductive reasoning I am led to believe D is the answer.
Hope this helps :)
