In some common expressions to do with place and time, generally countable nouns act like uncountable nouns and the article is omitted. 'Home' is where the speaker resides hence it does not need to be specified and the article is not used here. 'The' needs to be removed from the sentence hence option A is incorrect. Option D is correct as the sentence in the option has omitted the article 'the'. Options B and C include articles (a, an) used for non-specific nouns, 'home' is not a non-specific noun because it belongs to the speaker. Since we know that the home was his home, we can't use any of these articles, they're both incorrect.
