The most likely combination between Strontium (Sr) and Iodine (I) is represented by the formula **SrI2**.
This is because Strontium is a Group 2 metal that typically forms a +2 charge, and Iodine is a Group 17 nonmetal that typically forms a -1 charge. To balance the charges, one Strontium ion (+2) will combine with two Iodine ions (-1 each). Therefore, the correct chemical formula is **SrI2**.
