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 :)

<h3>Further explanation
</h3>
Humans impact the environment in so many ways such as overpopulation, overfishing, pollution, and deforestation. This condition leads to many other problems: poor air and water quality, climate change, and soil erosion. Increasing population means increasing demand for consumption that may destroy the natural resources and environment.
The government or an organization creates environmental policies to regulate environmental issues and to reduce human impact on the environment. According to McCormick environmental policy is “any action deliberately taken to manage human activities to prevent, reduce, or mitigate harmful effects on nature and natural resources, and ensuring that man-made changes to the environment do not have harmful effects on humans or the environment.”
The policy regulates the use of resources and to reduce pollution to promote human welfare and protect natural resources. Some example of environmental policy, governments forbade the use of hazardous substances in agriculture or apply maximum emission levels for the industry to ensure minimum environmental quality.
