<u>B. Spores</u> are involved in both sexual and asexual reproduction.
<h2>Explanation:</h2>
In science, a spore is a unit of sexual as well as asexual proliferation that might be adjusted for dispersal and for endurance, frequently for expanded timeframes, in troublesome conditions.
Bacterial spores are not part of a sexual cycle but rather are safe structures utilized for endurance under horrible conditions. Under good conditions, the spore can form into another living being utilizing mitotic division, delivering a multicellular gametophyte, which inevitably proceeds to create gametes.
