Answer:
<em>Option 'D' is correct.</em>
Step-by-step explanation:
Since we have given that
We will first find the "Discrimination":
Since discriminant is less than 0 i.e. D<0.
So, there will no real roots.
Hence, D = -28 and there is no real roots.
Therefore, Option 'D' is correct.

Answers with detail are given below.
Explanation:
C₆H₁₂O₆ → 2C₂H₅OH + 2CO₂
Anaerobic respiration in plants produced ethanol which if accumulate then cause the harmful effect in plants. It is also occur in some microorganisms such as yeast.
C₆H₁₂O₆ → 2C₃H₆O₃
Anaerobic respiration in animals pyruvate converted into lactic acid and it is not as harmful as ethanol in plant if accumulate. It is produced during exercise. It can produce the cramps which can be cured with massage.
C₆H₁₂ + O₂ → CO₂ + H₂O
This reaction is the combustion reaction of cyclohexane. Cyclohexane burnt in the presence of oxygen and form water and carbon dioxide.
