check grammar error before check meaning logic.
in A, "by..." and "making..." are both modifiers. 2 modifier never stand side by side because they can not modify each other. they need a noun modified, which is in between.
in B, "so that" must be preceded by a clause not a preposition phrase.
in D, "which" as not logic referent because "makes" is singular.
in E, 'that" refers to "plants" before to " technics".
