B and D: from when agriculture began to 1950
Here, when agriculture began is a noun clause serving as the object of from.
It could be argued that when agriculture began and 1950 are in fact parallel because each is a noun form.
That said, the construction in the OA -- from the beginning of agriculture to 1950 -- seems better, since it is avoids linking a clause (when agriculture began) to a non-clause (1950).
