Since 8 items have a low correlation with the total, it is recommended to delete these items to improve the homogeneity of the instrument. Retaining only the 17 items with higher correlation will improve the reliability and validity of the instrument. Option A is not recommended because the low correlation items will affect the reliability and validity of the instrument. Option B is not necessary as the instrument can be used with good results after deleting the 8 items. Option C is not recommended because deleting the other 17 items will significantly reduce the length of the instrument, resulting in a loss of content coverage.
