Option (a): This option strengthens the argument by suggesting that the company's leadership has a consistent bias in favour of flexible work arrangements, including the new work-from-home policy.
Option (b): While this option provides background information, it does not directly support the argument that the company is biased in favour of implementing the work-from-home policy.
Option (c): This option provides direct evidence of employee preference for the work-from-home policy, supporting the argument that the company is biased in favour of implementing it.
Option (d): This option suggests a correlation between productivity and support for the new policy but does not directly address the bias of the company.
Option (e) While this option suggests industry trends, it does not directly address the bias of the company in implementing the work-from-home policy.
Hence, the correct answer is option (c).
