{'honey': [2, 0, 0, 0], 'sugar': [0, 0, 0, 1], 'bacteria': [4, 1, 2, 3], 'bacterial attack': [3, 0, 0, 0], 'high osmotic strength': [1, 0, 0, 0], 'oxygen': [3, 0, 1, 0]}

Option 1 suggests that bacteria cannot survive in honey because there is no oxygen present. However, this is not true as bacteria can survive in oxygen-deprived environments.

Option 2 states that honey contains natural antioxidants that prevent bacterial attacks. While honey does have some antimicrobial properties, it is not solely due to antioxidants. The main reason honey has antimicrobial properties is explained in option 3.

Option 3 correctly explains why honey does not decay. Honey has a high osmotic strength, which means it has a low water content. Bacteria cannot survive in an active state in a solution with high osmotic strength because the water is drawn out of the bacteria, leading to their death.

Option 4 is incorrect as option 3 is the correct explanation.

In conclusion, the correct explanation for why honey does not decay is option 3: bacteria cannot survive in an active state in a solution of high osmotic strength as water is drawn out.
