Best answer
The correct choice is (c) 100

Easiest explanation: Iodine number is defined as number of grams of iodine needed for the iodination of 100 grams of oil or fat. Iodine numbers are often used to determine the amount of unsaturation in fatty acids. This unsaturation is in the form of double bonds, which react with iodine compounds. The higher the iodine number, the more C=C bonds are present in the fat.
