The correct option is A Mr. Bartholomew being a visionary, he brought about a change through peace rather than violence.
The absolute construction is a grammatical construction where the absolute (including a participle) modifies an entire sentence.
A
nominative absolute is a free standing part of a sentence that describes
the main subject and verb of that sentence. It can be placed before or
after the sentence, and is usually a non-finite clause that does not
express the tense of the sentence.
Option B contains the absolute construction "Mr. Bartholomew being a visionary" which modifies the clause that follows. hence option B is correct.
Option A does not use the absolute construction, it uses the Illative conjunction 'therefore'. Hence A is incorrect.
Option C also does not use the absolute construction, it uses the subordinating conjunction 'because', hence C is incorrect.
Option D is incorrect because the answer lies in B.
