The word ``inexorable" means something that cannot be stopped or resisted, often used to describe demands or forces that are relentless or unyielding.
- Option A: ``Unreasonable" refers to demands that are not justified or rational, which is not the most accurate match for ``inexorable." While the demands may be unreasonable, the term ``inexorable" emphasizes the unstoppable nature of the demands, not necessarily their rationality.
- Option B: ``Relentless" is the correct synonym for ``inexorable." Both words describe something that cannot be stopped or appeased, suggesting that the workers' demands were continuous and unyielding, leading to the closure of the company.
- Option C: ``Monetary" refers to something related to money, which is not relevant to the context of the demands being described as ``inexorable." - Option D: ``Violent" refers to physical force or aggression, which is not implied by the word ``inexorable." Thus, the correct answer is Option B.
