Which combination of statements regarding pteridophytes and their reproduction is correct?

Which of the following statements about bryophytes and their reproduction is correct?

Assertion (A): Gymnosperms produce both microspores and megaspores. | Reason (R): In gymnosperms, pollen grains develop within the microsporangia and are highly reduced.

Assertion (A): Algae are classified under the plant kingdom due to their autotrophic nature. | Reason (R): Cyanobacteria, also referred to as blue-green algae, are included in the plant kingdom.

Assertion (A): Pteridophytes have a dominant sporophyte stage in their life cycle. | Reason (R): The sporophyte in pteridophytes is differentiated into true root, stem, and leaves.

Assertion (A): Algae are important primary producers in aquatic ecosystems. | Reason (R): Algae carry out photosynthesis, contributing significantly to carbon dioxide fixation.

Assertion (A): Angiosperms are classified separately from gymnosperms despite both bearing seeds. | Reason (R): Angiosperms have flowers that develop specialized structures for pollen and ovules.

Assertion (A): Bryophytes are commonly found growing in dry areas. | Reason (R): Bryophytes require moisture for their gametophytes to thrive.

Assertion (A): Algae are primarily autotrophic and possess chlorophyll. | Reason (R): Algae are complex multicellular organisms that require soil to grow.
