(A)than in either Sweden or Finland - correct parallelism
(B)than either in Sweden or Finland - either in Sweden or in Finland is correct...
(C)than those in Sweden or Finland - increase is singular, so use of those is incorrect.
(D)than among those in either Sweden or Finland - same reason as C
(E)than it was either in Sweden or Finland - same as B

In B, the absence of the preposition 'in' before Finland breaks the rule of correlative conjunction parallelism. Either in Sweden or in Finland is the correct parallel expression.

Between A and B, any good explanation on the difference between both?

Would be happy to throw some Kudos out there

Cheeers!

In 1997 the frequency of calvings among dairy cows increased across Northern Europe; this increase was more apparent in Norway than [u]either in Sweden or Finland.

In option B, Suppose we were to remove either ... or .. construction and write the stem as two separate clauses, we would have,
This increase was more apparent in Norway than in Sweden; this is right.
This increase was more apparent in Norway than Finland; this is wrong as increase is compared with Finland.

Hope this clarifies.

In 1997 the frequency of calvings among dairy cows increased across Northern Europe; this increase was more apparent in Norway than in either Sweden or Finland.

There is some error in transcription. The underlining should start from --than in—after Norway.

(A)than in either Sweden or Finland -- Correct
(B)than either in Sweden or Finland --- parallelism problem
(C)than those in Sweden or Finland --- plural –those- is wrong
(D)than among those in either Sweden or Finland --- same as in C
(E)than it was either in Sweden or Finland -- parallelism error

options B and E have parallelism errors
options C and D have incorrect plural usage of ' those '
Sentence is correct as it is

In 1997 the frequency of calvings among dairy cows increased across Northern Europe; this increase was more apparent in Norway than in either Sweden or Finland.

My analysis is below:
Intended meaning
This sentence tries to compare the increase of frequency of calvings among cows in Norways to the increase in Sweden or Finland. It says that the increase of frequency of cow calvings was more apparent in Norway than (it was) in either Sweden or Finland.

Error analysis
No errors.
1. Parallelism: Either X or Y = Either Sweden or Finland. OK
2. Comparisson: the sentence correctly compares the apparent increase of frequency of calvings in Nowray to that of either Sweden or Finland.

(A)than in either Sweden or Finland. Correct
(B)than either in Sweden or Finland. Incorrect. Either in X or Y
(C)than those in Sweden or Finland. Incorrect. Pronoun number error.
(D)than among those in either Sweden or Finland. Incorrect. Pronoun-number error: those (increases) in - plural
(E)than it was either in Sweden or Finland. Incorrect. Either in X or Y

Hope this help!
