Select the set of terms that is related to the gynoecium:

The correct answer is Option (1)-  Stigma, ovule, embryo sac, placenta.

• Gynoecium refers to the female reproductive part of a flower.
• Stigma is the part of the pistil where pollen lands and germinates.
• Ovule is the structure inside the ovary that develops into a seed after fertilization.
• Embryo sac is the female gametophyte within the ovule, where fertilization occurs.
• Placenta is the tissue in the ovary that connects the ovules to the ovary wall.

These structures are all directly related to the female reproductive system of a plant. Other options mention structures like tapetum (associated with male parts) and stamen (male reproductive organ), which are not part of the gynoecium.
