I think that correct answers are:
<span>Some of them lose their leaves in winter. (i.e. <span><em>Larix</em></span>)</span>
<span>They include the tallest plants (i.e<em>.Sequoia)
</em>I don't think they are the oldest type of seed plants, since in the past the classes like progymnosperms and seed ferns existed prior to the gymnosperms. But question isn't absolutely clear to me and I can't be 100% sure.
All of the gymnosperms have seeds unless human grows some seedless variant.
Gymnosperms don't have flowers like angiosperms do, but some people think that cone is kind of flower.
Male cones produce pollen, not female.
Hope I helped :)

In the diagram we see a cell plant, with a few structures numbered:
0. Vacuole
,
1. Chloroplast
,
2. Nucleus
,
3. Cell wall
The answer options correspond with the functions of these structures:
0. Vacuole- Has secretory, excretory, and storage roles (B)
,
1. Chloroplast - It makes the photosynthesis (D)
,
2. Nucleus - Serves as the control center of the cell and contains the genetic information (A)
,
3. Cell wall ,- ,Provides structural support to the cell (C)
