Anther and filament are the parts of
-
Style
-
Stigma
-
Stamen
-
Ovary
The style is the part of the pistil which leads to the formation of the pollen tube.
Stigma is the part of the pistil which holds the pollen.
Stamen is the male reproductive part of the flower which is made up of two parts the filament which is a stalk that attaches to anther bilobed structure that forms pollen grains.
The ovary is the main female part that leads to the formation of an ovum.
So, the correct option is 'Stamens'.
The part of the plant which produce pollens are
-
Ovules
-
Anther
-
Filament
-
Both B and C
Anther is the bilobed structure that forms pollen grains which are attached with a stalk known as filament and they combine to form the stamens which are known as the male reproductive part of a plant.
Some example are given below how many of them have both following characters?

Stamens are also called
-
Calyx
-
Corolla
-
Androecium
-
Gynoecium
- Calyx which is considered as the outermost whorl and its unit is known as sepals and are green in color helps in protection of flower.
- Corolla is the second non-essential unit and is composed of petals and are colored and helps to attract pollinators.
- Stamens or androecium are the male reproductive part and responsible for the production of pollen grains (male gamete).
- Carpels or gynoecium are the female reproductive part and produce ovum (female gamete).
Which of the following characteristics are associated with petals?
-

The bisexual flowers contain both
-
Pistil and stamen
-
Ovary and anther
-
Pistil and ovule
-
Ovary and stamen
Stamen or androecium are the male reproductive part and responsible for the production of pollen grains (male gamete). Pistil or gynoecium are the female reproductive part and produce ovum (female gamete). If both the organs are present it is called bisexual flower. If one of them is present the flower is referred to as unisexual.
So the correct option is 'Pistil and stamen'.
Study of flowers is

The male part of the flower is known as
-
Filament
-
Anther
-
Stamen
-
Pistil
Stamens or androecium are the male reproductive part contains filament which is a slender stalk and anther is a bilobed structure which is responsible for the production of pollen grains (male gamete).
