Which of the following option is correct regarding conditions of adequate decomposition? (Assume R1∪R2∪R3∪ .... Rn ≡ R).
A. R1⋈R2⋈R3⋈ .... Rn ≡ R, and F1∪F2∪F3∪ ...∪ Fn ⊂ F respectively
B. R1⋈R2⋈R3⋈ .... Rn ⊃ R and F1∪F2∪F3∪ ...∪Fn ≡ F respectively
C. R1⋈R2⋈R3⋈ .... Rn ≡ R and F1∪F2∪F3∪ ...∪Fn ⊃ F respectively
D. None of the above
