Millions of identical copies of a plant can be produced using new tissue-culture and cloning techniques.
If plant propagation by such methods in laboratories proves economical, each of the following, if true, represents a benefit of the new techniques to farmers EXCEPT:
(A) The techniques allow the development of superior strains to take place more rapidly, requiring fewer generations of plants grown to maturity.
(B) It is less difficult to care for plants that will grow at rates that do not vary widely.
(C) Plant diseases and pests, once they take hold, spread more rapidly among genetically uniform plants than among those with genetic variations.
(D) Mechanical harvesting of crops is less difficult if plants are more uniform in size.
(E) Special genetic traits can more easily be introduced into plant strains with the use of the new techniques.

i will say C.
The aim of the new techniques are to produce many identical copies of the same plant. C says that disease and pests cause more damage to plants that are uniform, i.e. identical i.e. exactly what will be the result of the cloning techniques.
This is not helpful to the farmers at all.
