Choose the most appropriate option opposite in meaning to the underlined words. Measures were taken to authenticate the number of the booklets received?

Answer Details

The opposite of "authenticate" would be "discredit". "Authenticate" means to verify the authenticity or genuineness of something, while "discredit" means to cast doubt on the truth or reliability of something. Therefore, measures taken to discredit the number of booklets received would mean actions taken to question or invalidate the number of booklets received.
