这道题考查的是对文章主旨和作者意图的理解。我们来逐步分析：

题目：

Why did the author and his colleagues launch the Out of Office Email Generator?

选项分析：

A. To enable busy employees to spend less time checking emails.

这个选项说的是“让忙碌的员工少花时间查邮件”。虽然“Out of Office”（不在办公室）邮件通常用于自动回复，告诉别人你暂时不处理邮件，但这个选项并没有直接点出作者和同事开发这个工具的真正目的。它关注的是“员工少查邮件”，而不是“休息时间的尊重”。

B. To ensure employees as well as employers truly have time off.

这个选项说的是“确保员工和雇主都能真正休息”。这更贴近“Out of Office”邮件的核心目的：让人们在休假时真正能够脱离工作，而不是被邮件打扰。如果这个工具能自动发送不在办公室的回复，就可以帮助员工和雇主都尊重彼此的休息时间。

C. To stop managers from talking about how busy their teams usually are.

这个选项说的是“阻止经理们谈论他们团队有多忙”。这与“Out of Office Email Generator”的功能关系不大，属于无关选项。

D. To encourage both employers and employees to answer emails promptly.

这个选项说的是“鼓励雇主和员工尽快回复邮件”。这与“Out of Office”邮件的目的正好相反，因为这种邮件正是用来告诉别人你暂时不会回复邮件的。

正确答案：

✅ B. To ensure employees as well as employers truly have time off.

答案解析：

作者和同事开发“Out of Office Email Generator”的目的，是为了让人们在休假期间真正能够“离线”，不被打扰。这不仅有助于员工的休息，也帮助雇主尊重员工的休息时间，从而实现工作与生活的更好平衡。因此，选项 B 最准确地反映了他们的初衷。

最终答案：

$\boxed{B}$
