option: D (It was designed in france in 1791) is correct.

Step-by-step explanation:

" Advantage, benefit, profit all mean something that is of use or value. Advantage is anything that places one in an improved position, especially in coping with competition or difficulties" .

            Hence option (a),(b) and (c) are correct.
