Answer:

The correct answer is - oxalic acid.

Step-by-step explanation:

Oxalic acid and phytic acid are also components found in the foods like spinach. These components of the spinach reduce the bioavailability of the calcium and iron present in these leafy food sources.

Oxalic acids inhibit the absorption of calcium by bind to minerals, calcium, or iron and make mineral oxalate, in the gut, and prevent the body from absorbing them.
