Final answer:
The correct answer is C) Logograms, which are symbols representing a word or syllable within logographic writing systems like Egyptian hieroglyphics.
Step-by-step explanation:
The terms in question refer to ancient writing systems. Both pictographs and ideographs are methods of visual communication using symbols and images. A pictograph is a stylized image that represents an idea, while an ideograph combines multiple pictographs to express a more complex idea or concept. The answer to the student's question is C) Logograms. Logograms are signs that represent a word or a syllable, examples of which can be seen in writing systems like Egyptian hieroglyphics and Mayan glyphs, which are known to be logographic because they use signs to communicate entire words or syllables. Meanwhile, a syllabary is a set of written characters that represent syllables which together make up words.
