The correct option is B Absence of scolex hooks and uterine branching.
Taenia saginata is typically larger, longer, with more proglottids, more testes, and higher branching of the uteri compared to Taenia solium. Taenia saginata does not have any hooks on its scolex, unlike Taenia solium. Taenia saginata and Taenia solium both have male and female reproductive organs. So the correct answer is 'Absence of scolex hooks and uterine branching.'
