A) test-retest
B) alternate-form
C) split-half from a single administration of the test
D) split-half from two independent testing sessions

Split-half from a single administration of the test would result in the least appropriate estimate of reliability. This is because the split-half method involves dividing the test into two halves and comparing the scores on each half, which is not possible with a single administration of the test. Test-retest and alternate-form methods involve administering different forms of the same test to the same individuals, or administering the same test to the same individuals on two different occasions, which allows for comparisons of scores and estimation of reliability. Split-half from two independent testing sessions involves administering the test twice to the same individuals and comparing scores, which also allows for estimation of reliability.
