Answer
This option suggests that vitamin C is more soluble in fats than in water, which contradicts the common understanding that polar substances are generally more soluble in water. Additionally, calling it a good oxidant is not supported by the structural analysis.
Step 2
B. fats than in water and is a good reductant.

Answer
Similar to option A, this option incorrectly asserts that vitamin C is more soluble in fats. The structure indicates it is likely more hydrophilic, thus more soluble in water.
Step 3
C. water than in fats and is a good oxidant.

Answer
While vitamin C could be a good oxidant, this option again misplaces the solubility preference towards fats rather than water.

Answer
This option correctly identifies that vitamin C is likely more soluble in water due to its hydroxyl (-OH) groups which are polar, enhancing solubility in aqueous environments. Additionally, vitamin C acts as a good reductant, which is consistent with its antioxidant properties.
