You can either come with me now nor walk home later.The word which does not fit in the sentence correct order is:

Explanation

Option D is correct. The sentence uses 'either' but incorrectly pairs it with 'nor' instead of 'or'. The correct conjunctions would be 'either/or' or 'neither/nor'. Therefore, 'nor' does not fit in the sentence.Options A, B, and C are incorrect because they do not disrupt the grammatical integrity of the sentence. 'Can', 'either come', and 'now' can all be part of a grammatically correct sentence, while 'nor' creates a mismatch in conjunction pairing.
