1. The problem asks to identify which pair is C.P.C.T.C., which stands for Corresponding Parts of Congruent Triangles are Congruent. 2. C.P.C.T.C. applies when two triangles are proven congruent, meaning all their corresponding sides and angles are equal. 3. In the given figure, point O is inside triangle LMT, and segments LO, MO, and TO connect O to vertices L, M, and T. 4. To use C.P.C.T.C., we first need to establish congruence between two triangles formed by point O and vertices of triangle LMT. 5. For example, if triangles LOL' and MOM' are congruent (where L' and M' are points on the figure), then corresponding parts like angles or sides in these triangles are congruent. 6. Without additional information about the figure or congruence proofs, the general answer is that pairs of corresponding sides or angles in congruent triangles involving point O and vertices L, M, T are C.P.C.T.C. 7. Therefore, the pair connected by line segments from O to L, M, and T that correspond in congruent triangles are C.P.C.T.C.
