Answer: D. to inform readers about Blair's apology
Explanation:
The article excerpt provides information about Blair's apology in an unbiased way, meaning that it doesn´t intend to convince the reader of whether an apology was in order or not.
Option A is incorrect because the idea that British diplomats had allegedly been working non-stop is how Blair, and not the article, intends to persuade people not to blame them. Option B is incorrect because the article doesn´t ask or even hint for people to help British survivors. Option C is incorrect because the article is not meant to explain why Britons were deserted, but to inform how Blair considers they were not deserted at all.
