The correct answer is:

∠LOA ≅ ∠LMA

Step-by-step explanation:

AAS, or angle-angle-side, states that if two angles and the non-included side of one triangle are congruent to the corresponding two angles and non-included side of a second triangle, then the triangles are congruent.

We have an angle and a side. Out of the remaining two angles, the ones that would make the side marked, LA, non-included are LOA and LMA. This must be the missing information.
