Letter A. Explanation: the others just ask questions instead of giving you a fact that happened in the prompt so you can have a cause.
Source B is more credible because it is from a government site, so it is meant to inform. It has a quote that shows drones are in debate.
At first look, the sources seem similar. They both were written around the same period and the URL appears almost identical. However, it is important to notice that source A is from a website ending in ".net," while source B ends in ".gov." Government websites are always more credible than a website ending in ".com" or ".net." Also, source A has advertisements, which means it is mostly for entertainment. In comparison, source B has a quote from President Obama. Since the research is about the invention of drones and their controversial uses, source B is also more helpful since the title specifically mentions the rules and misuse of drones.
Answer: Conscience
Our conscience is the emotional and rational reactions we have due to our moral conduct. It is the good feeling we get when we perform something that we consider to be good, and viceversa. It is deeply personal and it is formed through our life experiences, our culture, and several other factors.
Conscience is often referred to as our "inner voice" or as a "moral compass." This comparison with a compass is due to the fact that most people use their conscience as a way to orientate themselves when they feel they are off course.
