The correct answer is option 1, the dry stigma. The saffron plant, scientifically known as Crocus sativus, produces a spice called saffron. Saffron is obtained from the plant`s flowers. More specifically, it is the dry stigma of the saffron flower that is used to obtain the spice.

The stigma is the receptive part of the flower`s female reproductive system. It is the part of the flower where the pollen is supposed to land in order for fertilization to occur. In the case of saffron, the stigma is dried and then used as a spice. The dried stigma of the saffron flower is known for its vibrant red color and distinct flavor.

When harvesting saffron, the flowers are carefully picked by hand, and the red stigmas are plucked out. These stigmas are then dried to reduce their moisture content and enhance their flavor. It takes a large number of flowers to obtain a small amount of saffron spice, which contributes to its high price in the market.

To summarize, saffron spice is obtained from the dry stigma of the saffron plant.
