B. Ruben
C. Jean Senebier
D. Julius Robert Mayer

Answer

A

Explanation

In 1930 C.B. Van Niel proved that, sulphur bacteria use `H_(2)S` (in place of water) and `CO_(2)` to synthesize carbohydrates as follows:
carboydrates as follows :
`6CO_(2)+12H_(2)toC_(6)H_(12)O_(6)6H_(2)O+12S` ltbr this led van niel to the pastulation that in green plants, water `(H_(2)O)` is utilized in placed (S). He indicated that water is electron donar in photosynthesis.
`6CO_(2)+12H_(2)OtoC_(6)H_(12)O_(6)+6H_(2)O+6O_(2)`
