Answer 1

Hint: The biggest diamond weighs 3,106.75 carats and is the largest gem-quality rough diamond ever found. Currently it is located in the tower of London in the British Sovereign's Royal Sceptre. Its mine of origin is Premier Mine. Its Owner is Queen Elizabeth II.

Complete Step by step answer:
The biggest diamond ever found is cullinan. So the correct option is option (A).
Although it's a fact based question still let’s see why other options are not correct.
Option (B) is Kohinoor.
Kohinoor is among one the largest cuts of diamond. Since its weight is 105.6 carat which is way lesser than cullinan therefore it is not the biggest diamond ever found. The origin of Kohinoor is the Kollur mine. Kohinoor’s country of origin is India.
Option (C) is bituminous.
Bituminous is a form of rock. Bituminous coal is also called black coal. Bitumen coal contains a tar-like substance called bitumen and bitumen coal is relatively soft coal. Bituminous is used in building of roads, waterproofing, roofing, etc.
Option (D) is peat.
Peat is nothing but just sphagnum. Sphagnum is a moss which comes under the class bryophytes of kingdom plantae. Peat is used as an alternative to firewood and used as fuel. Peat is also used for cooking in households.

Note: Don’t get confused between Kohinoor and cullinan while thinking which one is biggest. Kohinoor is the largest cut of diamond but the question is asking about the biggest diamond so Kohinoor can’t be its answer. Another point to keep in mind is the weight of Kohinoor and cullinan to find out which one is bigger when compared to the other one. Cullinan weighs way more than Kohinoor.
