Answer:
The statement 'A 1993 study showed that teachers tend to favor males over females, thereby creating an inequality in mixed-gender schools' provides the best supporting evidence for the claim.
Explanation:
Statement D best supports the claims because it provides evidence based on researches and data. A hypothesis statement or claim is always considered to be true when it is supported by sufficient researches and statistical data. Statement D is using research and data from a 1993 study to claim its point. Hence, it is the best statement that supports the claims.
The other options do not provide any research or data study to support their claim hence, other options are wrong.
