Answer: B. He received an honorable discharge in 1944 after being acquitted of all charges
Step-by-step explanation:
Wordiness is a common mistake made by people when writing and wordiness has to do with the use of too many words or when the writer uses abstract words. One effect of wordiness is that it may lead to frustration on the part of the reader.
In the sentence "He later received an honorable discharge in 1944 after being acquitted of all charges at the court-martial", time was expressed by the writer using "1944" and "later". This is wordiness as the same thing is repeated using different word.
Also, another wordiness was when the writer used "acquitted of charges at the court". Adding "Thus at the court" wasn't necessary because we know that someone acquitted of charges would have definitely happened at the court.
Based on the above analysis, option B " He received an honorable discharge in 1944 after being acquitted of all charges" eliminate wordiness.
