This question asks about the potential outcomes framework and what we observe for a unit that receives the treatment.
Option 1: True. In the potential outcomes framework, each unit has potential outcomes Y1 (if treated) and Y0 (if not treated). When a unit actually receives the treatment, we observe its realized outcome under treatment, namely Y1. The other potential outcome, Y0, remains unobserved for that unit due to the fundamental problem of causal inference, but the observed data for a treated unit is indeed Y1. 
Option 2: False. Saying we observe something other than Y1 for a treated unit would contradict the setup: the actual observed outcome under treatment is Y1, so claiming it would be something else is incorrect. This option misstates what is observed when treatment is applied. 
Option 3: Don't Know. This option suggests uncertainty about what is observed; however, the standard causal model specifies that the treated unit’s observed outcome is Y1, so there is no ambiguity here in the formal statement. The correct interpretation is that Y1 is observed for treated units, not Y0 or some other value. 
In summary, the reasoning aligns with the core idea that treatment units reveal Y1, while the alternative potential outcome Y0 remains unobserved for those units. The other options conflict with this fundamental principle or introduce unnecessary ambiguity.
