In the English language, the normal order of words in a sentence is: subject + verb + object.
(When there is an indirect object, then the word order is: subject + verb + indirect object + direct object.) The subject is the performer of the action (verb) and the object is the receiver of that action.
The given sentence follows the normal word order subject (My boss) + verb (told) + object (me, to finish the presentation). ('Today' is an adverb.)
Option B is incorrect because the words are not in the required order, they're in the order: subject + direct object + verb + indirect object.
Option C is incorrect because the sentence isn't in the right order, the indirect object "me" is placed before the verb "told", whereas it should be placed after.
Option D is incorrect because the sentence is incoherent.
