Answer:

The CHO formed from Calvin Cycle during photosynthesis comes from reduction of CO2 with H+ of photolysis of water.

Therefore,since Plant 1 contains labeled Oxygen(from water) it will give radioactive Oxygen as the byproduct of its photosynthesis. It CHO is normal.

However,Plant 2, will contain radioactive CHO,because its radioactive CO2 will be reduced by H+  from photolysis of water to form radioactive labeled  carbohydrate(CHO)
