Assertion : Six molecules of `CO_(2)`and twelve molecules of `NADPH^(+)H^(+)` and 18 ATP are used to from one hexose molecule.
Reason : Light reaction result in formation of ATP and `NADPH_(2)`

Options

A. If both the asserition and the reasion are true and the reason is a correct explanation of the assertion
B. If both the assertion and reasoni s not a correct ecplanation of the assertion
C. If the assertion is true but the reason is false
D. If both the asseertion and reason are false

Answer

B

Explanation

Six molecules of `CO_(2)` enter Calvin cycle to produce one hexose molecule whereas `18 ATP, 12 NADPH + H^(+)` molecules are used up. The light reaction of photosynthesis results in ATP and `NADPH_(2)` formation.
