The trip's delay is because of all the fees not yet being collected.
Explanation:
The meaning of concise is "giving a lot of information clearly and in a few words; brief but comprehensive." So this is the best choice because this sentence is not using all unnecessary words such as 'is' and was' so the sentence is much more brief and comprehensive then all of the others so, this is the best choice.
B may be true but the real idea they are trying to get across is that, as time passes, more people speak up. This is seen in many cases. Especially in cases with media vs. honest citizens.
I would've chosen cheap at first but then thrifty means being cheap and using it for a cause, not wastefully. So that's why it best fits that sentence. Hope this helps!
