Final answer:
The Egyptian civilization used hieroglyphics for their writing and built the iconic pyramids as tombs for pharaohs.
Step-by-step explanation:
The pyramid-building civilization that used hieroglyphics as their form of writing is the Egyptians (c). Egyptian hieroglyphics were symbols that evolved from pictures into a complex writing system including alphabets. This form of writing was central to recording everything from tax records to sacred prayers, thereby playing a crucial role in maintaining the continuity of Egyptian culture for thousands of years. The Mayans also developed a sophisticated system of writing, which included hieroglyphic components, but they did not build the kind of pyramids associated with the question. They did create large stone pyramids but not in the same architectural style as the Egyptians. Maya hieroglyphics were logographic, using signs to communicate syllables or words.
