Female cone produce ____
A
spores
B
cones
C
pollen
D
eggs
Explanation: 

Detailed explanation-1: -Female cones (ovulate cones) contain two ovules per scale. One megaspore mother cell (megasporocyte) undergoes meiosis in each ovule. Three of the four cells break down leaving only a single surviving cell which will develop into a female multicellular gametophyte .

Detailed explanation-2: -Female pine cones use their woody structure to keep their seeds safe. They keep their seeds safe so the seeds can hopefully be pollinated and grow. Each female pine cone has numerous spirally arranged scales, with two seeds on each fertile scale.

Detailed explanation-3: -The female cone (megastrobilus, seed cone, or ovulate cone) contains ovules which, when fertilized by pollen, become seeds. The female cone structure varies more markedly between the different conifer families, and is often crucial for the identification of many species of conifers.
