Which one of the following plants will have many ovules in their gynoecium?

Watermelon

The correct answer is Option (3) → Watermelon

The gynoecium represents the female reproductive part of the flower. 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). The placenta is located inside the ovarian cavity. Arising from the placenta are the megasporangia, commonly called ovules. The number of ovules in an ovary may be one (wheat, paddy, mango) to many (papaya, water melon, orchids).
