Data Sufficiency — school assignment for T among {B, C, D, E, F} Statements: I. T does not study in the same school as either R or J. II. R and J study in schools D and F respectively. Choose the correct sufficiency option.

Combine the information From II: R = D, J = F. From I: T ≠ R and T ≠ J ⇒ T is not in D or F ⇒ T ∈ {B, C, E}.

Conclusion Three possibilities remain; neither statement alone (nor together) pinpoints a unique school. Neither I nor II is sufficient.
