Mr Goni has planted-
- i. maize
- ii. brinjal
- iii. sugarcane
Think it through first, then pick an option.
- a i and ii
- b ii and iii
- c i and iii
- d i, ii and iii
Answer and explanation
Correct answer: c i and iii
Maize (i) and sugarcane (iii) are C4 plants whose first stable substance is oxaloacetic acid; brinjal is not.
Why the other options are wrong
- a i and ii: ii is false: brinjal is a C3 plant, and the correct iii (sugarcane) is left out.
- b ii and iii: ii is false: brinjal's first stable substance is not oxaloacetic acid, and i (maize) is left out.
- d i, ii and iii: ii is false: brinjal is C3, so all three cannot be correct together.
