Answer:
Answer B
Step-by-step explanation:
The correct answer is B. Change historyans' to historians'. The word "historyans'" is a misspelling of the word "historians'". Historians are the people who study and write about history, so the word should be spelled correctly in order to convey the intended meaning of the sentence. The other options, A, C, and D, do not correct the misspelling of "historyans'" and would not improve the overall meaning of the sentence.
