Final answer:
The Malla period being the golden period of sculpture and painting is false; this period in Nepal's history is not usually linked to such a golden age of arts unlike Classical Greece, Gupta Empire, or Mughal Empire periods.
Step-by-step explanation:
The statement that the Malla period is regarded as the golden period of sculpture and painting is False. The Malla Dynasty was a medieval-era ruling dynasty of the Kathmandu Valley in Nepal, not directly associated with a prominent golden age of art and sculpture that the question seems to imply.
In the context of the information provided, several periods such as the Classical Greece period, the Dutch Golden Age, and the Gupta and Mughal periods in India are known for their distinctive and flourishing art and sculptures.
For example, during the Gupta Period, there was a significant production of religious sculptures such as the iconic meditating Buddha, which did not represent the ruling class but rather the major religions of the time. Similarly, in the Mughal Empire, art was integral to the court, with a cultural tradition that revered art and prompted the production of illustrated books, albums displaying portraits, and colorful paintings.
