D. SSA
Explanation: SSA (two sides and a non-included angle) does not always determine a unique triangle — the "ambiguous case" can produce two different triangles (unless additional conditions apply, e.g. a right triangle (HL) or the given side/angle satisfy special inequalities). SSS, SAS and ASA are valid congruence theorems.
