According to the investigations of physiologists and psychologists,

A. nervousness has been found to be not an organic disease but a functional one, which is a critical distinction, for an organic disease implies impairment of the tissues of an organ, while a functional disease indicates only a disruption of its role
- modifier issue, which is incorrectly referenced. not reading the rest of the sentence as this is ruled out.B. nervousness, found to be an organic disease rather than a functional one, a critical distinction, because an organic disease implies impairment of an organ’s tissues, while a functional disease indicates only a role disruption
- this option is off. modifier issues with critical distinction.C. it has been found that nervousness is not an organic disease but rather is a functional one; while a functional disease indicates only a disruption of an organ’s role, an organic disease implies impairment of the tissues, a critical distinction
- issue with not A but 'rater' B. ruled out.D. nervousness has been found to be not an organic disease but a functional one; this distinction is critical, for an organic disease implies impairment of the tissues of the organ, while a functional disease indicates only a disruption of its role
- no major issues with this. even though there are multiple parts involved.E. nervousness was found to be not an organic disease but a functional one, a critical distinction, since impairment of the tissues of the organ is implied by an organic disease, while a functional disease indicates only a role disruption
- again, I think critical distinction has a modifier issue
