Quizplus · Accepted Answer

The Bikonta group is characterized by having two flagella, and the major eukaryotic lineages that form Bikonta are Alveolata, Stramenopila, Rhizaria, Plantae, and Excavata. Option B includes all of these major lineages, making it the best choice. Option A includes Amoebozoa and Opisthokonta, which are not part of the Bikonta group. Option C only includes Rhizaria, Plantae, and Excavata, which are not enough to form the Bikonta group. Option D only includes Amoebozoa and Opisthokonta, which are not part of the Bikonta group. Option E only includes Alveolata and Stramenopila, which are not enough to form the Bikonta group.
