Observe the given figure representing substances (P, Q, R and S) taken in or given out during photosynthesis and select the incorrect option regarding them.


AQ could be the gas which is fixed through photosynthesis to form carbohydrates whereas P could be the gas which is used by plants in respiration.
BP is the gaseous by-product of photosynthesis whereas S is carbohydrate formed by plants through photosynthesis.
CQ is taken up by plant leaves directly from atmosphere through minute stomata present in them whereas R represents water absorbed from soil through plant roots.
DR and S show unidirectional movement within the plant body, i.e., from source to sink.
