I would go with the answer E). Just because slavery ended years ago doesn't mean that's its still over even to this day, it use to be about gender as well back than where women couldn't vote but no one cares about that today, the things people care about is race because as the famous quote someone said, humans hate what they don't understand, so most races don't understand why people are all different, so they want to hate them since they don't understand and also get higher authority as well, but to get back to topic race is the most common thing today that encourages people to leave and migrate cause they might not feel welcome.
I belive the answer to the first one is no I would have to assume a habitual zone is one area on a planet. for example, an air conditioned building vs. the Savvanah dessert. However I am not sure maybe other answers will help more on this one. Sorry.... Earth-like planet would of course need water, plant life, animals, oxygen, fossil fuels etc. A challenge we would face on a travel to another liveable planet: do we have engough transportation? engough fuel to make it? How long can we live on this planet? Who or what else is present here? etc. Yes I do think they should discover a planet with earth like qualities befor investing in tools to get us to them. So money is not wasted. (make sure to put this into your own words )
