**Explanation:**

The Peacock Throne was indeed looted by Nadir Shah, making option B the correct answer. Here is a detailed explanation of how and why the Peacock Throne came into Nadir Shah's possession:

**The Peacock Throne:**
The Peacock Throne was a magnificent throne made for the Mughal Emperor Shah Jahan in the 17th century. It was adorned with precious gems, including rubies, diamonds, emeralds, and pearls, and was named for the life-sized peacocks that stood behind it, their tails dazzling with gemstones.

**Nadir Shah's Invasion:**
In the early 18th century, Nadir Shah, the ruler of Persia (present-day Iran), launched a military campaign to conquer vast territories, including the Mughal Empire in India. He sought to plunder the wealth and treasures of the Mughals, which included the Peacock Throne.

**The Battle of Karnal:**
Nadir Shah's invasion culminated in the Battle of Karnal in 1739. The Mughal Emperor Muhammad Shah was defeated, and Nadir Shah's army captured Delhi. The victorious Persian army then went on a rampage, looting and plundering the city.

**Looting of the Peacock Throne:**
During the sacking of Delhi, Nadir Shah's soldiers plundered the Mughal treasury and seized numerous valuable items, including the Peacock Throne. The throne's precious gems and jewels were torn off and carried away, leaving behind only the gold structure.

**Nadir Shah's Return to Persia:**
After the looting, Nadir Shah returned to Persia with his spoils, including the Peacock Throne. The throne was dismantled, and the precious stones were distributed among his soldiers and nobles.

**Fate of the Peacock Throne:**
The fate of the Peacock Throne's individual pieces remains unclear. Some gems were sold or traded, while others were passed down through generations. Over time, the gems from the Peacock Throne became scattered across different collections and private hands.

**Conclusion:**
In conclusion, the Peacock Throne was indeed looted by Nadir Shah during his invasion of the Mughal Empire. The throne, known for its exquisite beauty and valuable gemstones, was dismantled and its precious gems distributed among Nadir Shah's soldiers and nobility. Today, the fate of the Peacock Throne's individual pieces remains a mystery, with its gems scattered across various collections.

The original throne was captured and taken as a war trophy in 1739 by the Persian emperor Nadir Shah, and has been lost since. A replacement throne based on the original was commissioned afterwards and existed until the Indian Rebellion of 1857.
