The correct option is C

a-ii-1, b-iii-3, c-i-2

a-ii-1, b-iii-3, c-i-2.

Calcium provides strength to our teeth and bones and milk is a rich source of calcium. Iron is required for the formation of hemoglobin molecule which is the oxygen carrier of our body. Homemade kheer with jaggery is a good source of iron. Iodine is required for the synthesis of a hormone called thyroxin. Seafood kelp is an important source of it.
