The four main parts of a flower are the

• A. Stamen, Pistil, Petal, and Sepal
• B. Stems, Leaves, Roots, and Flowers
• C. Petal, Sepal, Stamen, and Pistil
• D. Stamen, Pistil, Sepal, and Pollen

Answer: (A)

Flowers have four main parts: the reproductive organs (stamen and pistil) and the outer parts that protect and attract (petals and sepals). The stamen is the male structure that produces pollen; the pistil is the female structure that contains ovules and leads to seeds after fertilization. Petals are usually colorful and draw in pollinators, while sepals protect the developing bud and support the flower’s parts. Naming stamen, pistil, petal, and sepal together covers the essential components of a typical flower, whereas other options mix in non-flower parts like stems, leaves, or roots or list pollen as a separate part, which isn’t a distinct flower component.
