Which is not a way to write concisely?
a. cut bloated words and phrases.
b. place modifiers at the beginning of the sentence.
c. choose precise nouns and verbs.
d. use active rather than passive voice.

The correct answer is B. Place modifiers at the beginning of the sentence. 

When writing concisely, it means you have to write in a brief yet informative manner. All of these choices could help: cutting bloated words and phrases, choosing precise nouns and verbs, and using an active rather than passive voice. Except for letter B which doesn't have anything to do with writing concisely.
