Read the following excerpt from a US court opinion:
```
(1987) (noting that "where the employer effectively proves that a claimant's disability has been removed altogether, it is not required to prove that suitable work was available to the claimant because it can be presumed that employment is generally available to able-bodied persons.") 7 . Where the Board has not taken additional evidence, our standard of review is limited to determining whether constitutional rights have been violated, an error of law has been committed, or necessary findings of fact are supported by substantial evidence. Haines v. Workmen’s Compensation Appeal Board (Clearfield County), 146 Pa.Commonwealth Ct. 437, 606 A.2d 571 (1992). 8 . See Rite Aid Corporation v. Workmen’s Compensation Appeal Board (Bupp), 112 Pa.Commonwealth Ct. 548, 552, 535 A.2d 763, 765 (1988) ; Economy Decorators v. Workmen’s Compensation

What is the most suitable continuation to the opinion? Your options are:
A. holding that because a suspension admittedly is a concession that disability is continuing  claimant need only show that the work provided by the employer on which the suspension is based is no longer available to claimant whereupon total disability payments must be reinstated as of the date of termination of that employment
B. holding that the burden of proof is on the claimant
C. holding claimant suffered permanent total disability where functional disability was only twentyfive or thirty percent claimant was fiftynine years of age claimant had little or no education and the injury kept the claimant from performing physical work
D. recognizing that in suspension situations when a claimants lightduty job ends under circumstances where neither the claimant nor the employer bears any culpability the employer must either find other suitable and available work for the claimant or resume payment of benefits
E. holding that claimant moving for summary judgment on its claim must conclusively prove all the essential elements of the claim and that claimant has the burden to show that there are no genuine issues of material fact and that claimant is entitled to judgment as a matter of law
