- AOnly I follows
- BEither I or II follows
- COnly II follows
- DNeither I nor II follows
Step-by-Step Solution
With X ≥ Y and Z ≥ Y, the relation between X and Z is undetermined, but 'X > Z' and 'X ≤ Z' are complementary and together exhaust all cases, so either I or II follows.
Answer: B) Either I or II follows
