Immediately after light becomes unavailable, the biosynthetic phase of photosynthesis continues for some time and then stops. If then, light is made available, the synthesis starts again. A logical conclusion of these observations will include:
| I: | Biosynthetic phase does not directly depend on the presence of light. |
| II: | Biosynthetic phase depends on the products of light reactions. |
| III: | Biosynthesis phase occurs only in the dark or in the absence of light. |
| 1. | Only I and II | 2. | Only III |
| 3. | Only II | 4. | I, II and III |
