[A] Kuder - Richardson reliability coefficient would also be .90, but the split-half reliability coefficient may differ from .90.
[B] Split-half reliability coefficient would also be .90, but the Kuder - Richardson reliability coefficient may differ from .90
[C] Both Kuder - Richardson reliability coefficient and split-half reliability coefficient would be .90.
[D] The correlation between odd and even parts of the test would be .90.
