Complete answer:
The stalk of the flower is defined as the lowermost part of the flower and it also has a part that is termed as a receptacle to which other parts of plants are attached. The stalk of the flower serves as a support for other flower parts like leaves, buds, etc

Now let us find solution from given options:
Petiole : A stalk that helps to attach a leaf to the plant stem and on which the flower is born is called Petiole. The leaves, the petiole may be long or the same leaves the leaf stalk is absent.
Pedicel : The presence of the pedicel flowers is termed as pedicellate. A pedicel of flowers which show the characteristics to bear a stalk is called a pedicellate flower.
Sessile : A flower that is present directly on the stem is termed as a sessile flower. It shows the absence of a stem.
Thalamus : Thalamus is basically the receptacle that is located in angiosperms at the base of flowers and it is the thickened part of the stem from which the various flowers grow. There are three types of flowers on the premises of relation to position in various types of floral organs
