Which scheme records the number of times that a word appears in a document?

Counting word occurrences is the essential idea here: it records how many times each word appears in a document. Count Bag of Words provides a vector where each entry is the exact number of appearances for that word, preserving the raw counts across the vocabulary. This makes it a direct representation of how often words show up, unlike Term Frequency, which would normalize those counts into frequencies rather than keeping the exact counts. A plain Bag of Words can be about presence/absence or counts depending on usage, but when you need the explicit number of occurrences for each word, the Count Bag of Words is the precise fit. A dictionary-based or heuristic approach doesn’t inherently produce per-word occurrence counts in a document, so it doesn’t match this requirement.
