Answer:
B. In fact
Explanation:
The transition word that would best clarify the relationship between the claim and the
evidence in these sentences is option B, "in fact".
This is because, it best connects the claim which says that schools needs to implement stricter school dress codes because it has certain advantages and the evidence which states that school uniforms have been shown to promote school spirit and a sense of belonging. It shows clearly that the evidence agrees with the evidence.
