The statement that best describes the Mayan writing system is:
"The Mayan writing system was the most evolved in the Americas."
The Mayan writing system is known for its complexity and sophistication, with a combination of logograms and syllabic signs, and is considered one of the most developed writing systems in ancient Mesoamerica. The other statements contain inaccuracies, such as the notion that all evidence of the writing system was destroyed by the Spanish, which is not true; while many texts were lost, some codices and inscriptions remain.
