The correct answer is the first option.
We can show that the 2 triangles are congruent by using vertical angles, to prove that m∠DCA = m∠TCS
Then by Alternating Interior Triangles, m∠A = m∠T and m∠D = m∠S
And finally, the sides AC and CS are equal, and DC = CT
Then we have 3 pairs of congruent corresponding sides and 3 pairs of congruent corresponding angles, which is the first option.
