Answer:
Several studies show a relationship between academic achievement and self-esteem.
Step-by-step explanation:
Pseudopsychology claims are psychological claims which are false, unfounded and not based on scientific/research results. These claims may sound persuasive and even true but they are indeed false. For example, people sometimes claim that white men are smarter and more intelligent than black men, this is a pseudo claim with no scientific backing.
Back to the question, the only option with a scientific/research claim is "Several studies show a relationship between academic achievement and self-esteem". The rest are just claims without scientific proofs, however persuasive they sound, they are at best pseudo claims.
