B. The introductory text in the sentence cannot stand alone.
A colon can only be used when the text before the colon can stand alone as a complete sentence. The text before the colon is "I need to stop at several places, including". Including causes this sentence to be a fragment and therefore the colon is not grammatically correct. Options A, B, and C are all incorrect statements about colons.
The statement that best explains the colon stated after the word 'including' should be removed as the introductory text is not seemed to be stand alone.
Option B is correct.
A sentence is said to be standalone when it is having a context or topic or where there is neither of it. It simply means the sentence which could be used individually.
Colon is the mark having two black dots placed vertically in a sentence. It is used when the text being written before the colon sign is entirely complete in itself. It should be removed from the sentence as the text placed before the colon, that is, the line stating I need to stop at several places including is not complete. The word including created a sense of incompleteness if the colon is used.
Therefore, the introductory text is not complete due to which the colon sign should not be placed.
