The gynoecium represents the female reproductive part of the flower. When gynoecium is having more than one pistils and the pistils are fused together, the condition is called:

Syncarpous

The correct answer is Option (1) → Syncarpous 

The gynoecium represents the female reproductive part of the flower. The gynoecium may consist of a single pistil (monocarpellary) or may have more than one pistil (multicarpellary). When there are more than one, the pistils may be fused together (syncarpous) or may be free (apocarpous). Each pistil has three parts, the stigma, style and ovary. The stigma serves as a landing platform for pollen grains. The style is the elongated slender part beneath the stigma. The basal bulged part of the pistil is the ovary. Inside the ovary is the ovarian cavity (locule).
