D. red algae​

Explanation:

Carpospores are diploid (2n) spores of red algae. A carposporangium (plural: carposporangia) is a sporangium that produces carpospores. Moreover, a tetraspore is a haploid (n) spore that germinates to produce a gametophyte (in red algae). Tetraspores are produced in groups of four in a tetrasporangium (plural tetrasporangia) during the life cycle of some species of red algae (Rhodophyta). These spores (tetraspores) are produced by meiosis.
