Hint: China, officially known as the People's Republic of China, is a country in East Asia (PRC). It is the world's most populous nation, with a population of approximately 1.4 billion people.
The Great Wall of China is a chain of fortifications built to protect ancient Chinese states and Imperial China from nomadic groups from the Eurasian Steppe. Border controls, enabling the imposition of duties on goods transported along the Silk Road, regulation or encouragement of trade, and immigration and emigration control are some of the other objectives of the Great Wall, in addition to protection.
Several walls were constructed beginning in the 7th century BC, with Qin Shi Huang (220–206 BC), China's first emperor, later joining selected stretches together. Just a small portion of the Qin wall has remained. Many subsequent dynasties constructed and sustained numerous stretches of boundary walls throughout the following centuries. The Ming dynasty (1368–1644) designed the most well-known parts of the wall.
Additional Information:The strictest sumptuary laws in Chinese history were enacted during the early Ming dynasty. Commoners could not wear fine silk or bright red, dark green, or yellow clothing, nor could they wear boots or guan hats. Women were not permitted to wear gold, jade, pearl, or emerald ornaments. Silk was also prohibited for merchants and their relatives. From the middle Ming-era onwards, however, these laws were no longer followed.
So, the answer is Option ‘D’ i.e, Ming dynasty.
Note: Following the fall of the Mongol-led Yuan dynasty, the Ming dynasty, officially known as the Great Ming, ruled China from 1368 to 1644. The Ming dynasty was China's last Han Chinese-ruled imperial dynasty.
