Explanation:

A SMART goal's "attainable" aspect means the goal is within reach, even if it requires effort. The first option describes the "specific" aspect (clear target). The second option is about the "measurable" aspect (criteria for progress). The third option is not a standard SMART characteristic. The fourth option correctly aligns with "attainable" (within reach with commitment).
