A graph G $G$ is called 3-choice-critical if not 2-choosable but any proper subgraph of 2-choosable. strongly fractional r $r$ -choosable ( a , b ) $(a,b)$ for all positive integers $a,b$ which ∕ ≥ $a\unicode{x02215}b\ge r$ . The strong choice number c h f s = inf { : $c{h}_{f}^{s}(G)=\text{inf}\{r:G$ } $\}$ This paper determines the graphs.
