For this kind of paragraph, it helps to treat each sentence as needing an "ingredient" from an earlier sentence, and then arrange them so no sentence uses something that has not been introduced yet.
Sentence "c" needs nothing before it, it simply announces that there are stages in strategy and implementation, so it works as the opening line. Sentence "a" needs a "stage" to be the first one it describes, which "c" provides, and it produces "data" as its own output. Sentence "b" needs that "data" to build strategies from, which only "a" has supplied by this point, so "b" cannot come before "a." Sentence "d" needs finished "strategies" to implement and monitor, which only exist after "b" has made them, so "d" has to be last.
Following this ingredient chain gives the order "c" first, "a" second, "b" third, and "d" last, since each sentence only uses material the sentence right before it has already produced.
So, the correct answer is cabd.
A different way to solve this is to track only the small linking words and repeated nouns in each sentence, ignoring the broader meaning, and use those alone to chain the sentences.
Following only the repeated words, data, strategies, and goals, from one sentence to the next confirms the same chain.
So, the correct answer is cabd.
