(A) likely to be at a severe disadvantage and is often unable to

(B) likely severely disadvantaged and often unable to

(C) liable to be severely disadvantaged and cannot often

(D) liable that he or she is at a severe disadvantage and cannot often（A）

(E) at a severe disadvantage, often likely to be unable that he or she can

In C, liable, followed by an infinitive, can legitimately be used to express probability with a bad outcome, but C is otherwise flawed as noted. D’s liable and E’s unable should be followed by an infinitive rather than by a relative clause beginning with that
