Which equation represents the process that occurs when the standard enthalpy of atomisation of iodine is measured?

$I2(s)→2I(g)\text{I}_2(\text{s}) \rightarrow 2\text{I}(\text{g})$

$12I2(l)→I(g)\frac{1}{2}\text{I}_2(\text{l}) \rightarrow \text{I}(\text{g})$

$12I2(s)→I(g)\frac{1}{2}\text{I}_2(\text{s}) \rightarrow \text{I}(\text{g})$

$12I2(g)→I(g)\frac{1}{2}\text{I}_2(\text{g}) \rightarrow \text{I}(\text{g})$
