Read colin's argument. nowadays, one often hears complaints that drones can invade people's privacy. but this is not true. flying drones is actually a sport. it requires coordination and technical skills like other sports. in fact, there should be professional drone-flying leagues. if people recognized this sport, they would no longer complain about where and when drone owners flew their drones. is colin's evidence relevant to his claim? yes, because he gives evidence that flying drones is a sport. yes, because it is on the subject of people owning and flying drones. no, because he only gives his own opinion rather than providing evidence. no, because it is about flying drones being a sport, not about privacy issues. answer is the last option (d)

the last option d is the answer.the reasons are clear.he wants to defend flying drones as an activity which does not invade people´s lives.in turn , after making the claim collin justifies the use of drones as a sport and mentions what it requires for doing so.collins also says that it should be advisable to have more organization for the ones who do this activity but never gives any evidence to support the claim that drones do not invade privacy.when collins tells about complaints against the time and place drones are used , he could be speaking about people being disturbed about the noise drones make or about using some public space meant for other activities and not exactly privacy.

the answer is b, it brings the reader closer to the action.

it would've been a if the word had been determined, not conceited

hope this
