请问关于代词指代的logical referent问题

wotaowoyao

发现OG有很多代词指代提都是说it has no logical referent,比如：

35. In June of 1987, The Bridge of Trinquetaille, Vincent van Gogh's view of an iron bridge over the Rhone sold for $20.2 million and it was the second highest price ever paid for a painting at auction.

(A)  Rhone sold for $20.2 million and it was

(B)   Rhone, which sold for $20.2 million, was

(C)  Rhone, was sold for $20.2 million,

(D)  Rhone was sold for $20.2 million, being

(E)   Rhone, sold for $20.2 million, and was

it in A has no logical referent

83. Any medical test will sometimes fail to detect

a condition when it is present and indicate that there is one when it is not.

(A)  a condition when it is present and indicate that there is one

(B)  when a condition is present and indicate that there is one

(C)  a condition when it is present and indicate that it is present

(D)  when a condition is present and indicate its
                presence

(E)   the presence of a condition when it is there and
                indicate its presence

OG解释说C中的it都能指代condition,A,B的it没有可指代的referent,还有这句话 its presence in D leaves the it in when it is not without a logical referent，我的问题是怎样判断代词出现有可以指代的前称呢，为什么A的it可以指代condition,D,E就不可以了？请NN现身解释一下我的困惑，不胜感激！
